Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a serial USB drive, especially a USB (Universal Serial Bus) ) Interface storage device, the mobile disk reserves at least one downstream port, which is conducive to the serial connection of other mobile disks or the multilayer topology connection of other downstream USB peripheral devices. [Prior technology] The internal function block of the conventional US B mobile drive (USB Drive) or flash drive is shown in Figure 4. Generally, a USB interface circuit 8 is used to connect the flash memory (F 1 ash M em〇ry ) 9 into. Among them, the data stored in the flash memory 9 can communicate with the USB bus of the host computer or other microprocessor devices through the USB interface circuit 8 to complete the data transmission operation. Because the early flash memory technology is not developed, its capacity cannot be made very large, making the capacity of early mobile disks quite limited. Today, large-scale files such as multimedia information are widely used. At present, the way to handle such large files is that users need to use backup software to store files on different USB drives or other recording media. Users must also pay attention to labeling The storage order of these USB drives or recording media, and then when reading files, they still need to be placed in and swapped to the reading device in accordance with their divided storage order. Obviously, this archiving method is not very efficient. Large files can be stored at once. The capacity of early mobile disks is insufficient, and you need to buy large-capacity mobile disks again. The old mobile disks are discarded, causing waste of memory resources. Therefore, the new generation of mobile disk technology needs to be considered. It can be used in series to expand the existing memory capacity to solve this embarrassing problem. On the other hand, the convenient use of USB has caused most computer cycles.

Giant __ amendment ...... .. 5. Description of the invention (2) ^ The edge device became a member of the USB family by joining the USB interface agreement. However, at present, most standard computer hosts only reserve two USB sockets. If a user plugs in a USB socket with a conventional old USB mobile disk, there is only one USB socket left. If the user wants to further expand several USB interfaces Computer peripherals need to connect a multi-port USBHub to meet the demand for USB sockets. For users, it is more difficult to purchase new hardware. Therefore, ordinary users choose to plug in USB sockets alternately. These peripheral devices are used alternately, but the inconvenience of using alternate plugs is still disturbing. Therefore, the new generation of mobile disk technology also needs to consider scalability issues, such as retaining at least the number of USB sockets reserved by the original computer host to facilitate plugging in other downstream USB peripheral devices. [Summary of the Invention] The main purpose of the present invention is to solve the above-mentioned problems and provide a cascadable USB mobile disk with upstream and downstream ports, which is beneficial to the interactive serial connection of other mobile disks or the multilayer of downstream USB devices. Topology connection. The mobile disk has a conversion circuit inside. When the device plugged into the downstream port is another serial USB mobile disk or an old USB mobile disk, the conversion circuit performs a serial control function to make the two mobile disks memorize. The device is connected in series; when the inserter is a general USB device, the conversion circuit changes its configuration to a USBHub and executes the hub action, so that the USB mobile disk memory device and the downstream USB peripherals can be separately connected to the computer host or other microprocessing USB bus communication of the device.

Description of the Invention (3 The mobile disc can also be plugged in separately for use of its built-in memory capacity, making the application of the present invention extremely flexible. In the arrangement for expanding the memory capacity, when the conversion circuit in the present invention performs the concatenation function, all of the serially connected u S Β mobile disk memory is combined into a single virtual memory space, and can be based on the interior of the mobile disk storage device. Marked as sequential execution of reading or writing of data in most serially connected US Β mobile discs, users of the present invention can not worry about the insertion order of each mobile disc 'mainly as early as the interior of each disc. The Firware code can control the reading or writing sequence of data by itself. On the other hand, the conversion circuit of the present invention can also automatically switch the downstream port to the function USB socket of the USB hub, providing any downstream USB peripheral computer peripheral equipment that can be expanded by hot plugging. Therefore, the present invention is a practical and advanced design. In addition to the functions of unlimited connection and expansion of memory capacity, it can also combine the memory capacity of the old USB mobile disk, and at least retain the number of USB sockets reserved by the original computer host. It is believed that those who apply the present invention can also obtain these advantages.

Description of the invention (5), when the device reads the aforementioned divided files, there is no need to-replace these action 'discs, especially when reading If the two inserters are both serial-connected USB removable disks when fetching files, and they are arbitrarily inserted differently from the original storage order, the order of the two inserted removable disks is distinguished by the flash memory marking order inside the removable disks. It is more important to judge the read order of the divided files, whether it is a single or a plurality of cascadable USB mobile disks of the present invention, it can retain at least the number of USB sockets reserved by the original computer host, so as to facilitate plugging in other Downstream USB computer peripherals. The downstream ports of the cascadable USB mobile disk according to the present invention can be designed in multiples, and each of the downstream ports can perform the above-mentioned serial cascadable USB mobile disk, or can be connected to other downstream USB computer peripherals Or a general USB flash drive. On the other hand, when the inserter is a general USB device, the conversion circuit 2 notifies the host computer of US st 〇st C ο ntr ο 1 1 er, changes its configuration to a USBHub to perform the hub action, and makes the flash Memory 4 and downstream USB peripherals can communicate with the USB bus of the host computer or other microprocessor devices respectively. The functions described above explain the convenience of the present invention in using the mobile disk. The downstream connection reserved by the mobile disk can be used in series with each other to expand the memory capacity. Therefore, most of this type of mobile disk can be formed by serial connection. Larger memory space; in the arrangement for expanding the memory capacity, when the conversion circuit 2 performs the serial control function, it can perform the reading and writing of data according to the internal marks of the flash memory 4 between the mobile discs. In order to form a virtual large-capacity hard disk, users can control the order or flow of data storage without having to worry about the insertion order of each mobile disk.

This function can more easily detach the downstream port and use the function of the upper moving disc. In addition to breaking the existing solution of the original video game US, it can be used to make the 12 hot-swappable equivalents alone. It can still be said to be flexible enough to be connected to the Flash brain host B computer. It can be said to be able to continuously connect other traditional uses. The inserted device is designed to defecate and can be full at the end. It can be used in a wide range of ways. Memory ^ The reserved U peripheral devices have a large number of USB mobile disks that can be connected in series. In terms of this, the mobile device of the present invention automatically switches to the US for any USB computer continuous serial connection. Most of those who can be stringed provide automatic switching to U for flexible use. For this type of storage capacity, the memory capacity of the memory space is limited, and the number of SB sockets is also provided to effectively use the old practicality and progressive production.
