Perfect solution for unrecognized USB devices

Questions about the use of USB2.0
1. Does win2ksp4, WINXP, SP1, and SP2 support USB2.0, respectively?
2. Is USB2.0 related to computer hardware interfaces? The USB on the laptop I bought six months ago should be 2.0, right?
3. If WINXP does not automatically support USB, where should I download the relevant drivers and software? It takes more than 20 minutes to copy a hard drive of several hundred megabytes.
4. "High-speed USB insertion of non-high-speed USB interface" is a common problem connecting the active hard disk to the host. How can this problem be solved?
5. Is USB2.0 only related to hard disk boxes? Because it is actually an IDE hard disk.
6. Many hosts (XP) cannot recognize my USB hard drive. How can this problem be solved? Is it a problem with the active hard drive?

Let's talk about one thing I know:
1. XP does not support USB2.0, SP1 and SP2.
2. Check whether your database is the master controller of usb2. If you bought it six months ago, it should be 2.0.
3. When you buy a mobile hard drive, you get a drive disk, which is available there, or you can download it from the driver's home.
4. "High-speed USB insertion of non-high-speed USB interface" indicates that your machine is the master controller of usb1 or you have not upgraded to SP1. There are two solutions for the former, one is to upgrade your master controller, and the other is to buy a PCMCIA to usb2 converter. After installing the SP1 Patch on Windows XP, the latter can support USB for transmission.
5. Correct.

I. Even if the driver is correctly installedProgramIt is also possible that the system cannot detect the USB hard disk. This is mainly because the default CMOS port of the motherboard is disabled. If it is not set to enabled, windows cannot detect the mobile hard drive. To solve this problem, we can restart the system, enter the CMOS settings window, and set "Assign IRQ for USB" to "enable" in the "PNP/PCI configuration" column ", in this way, the system can allocate available interrupt addresses to the USB port.

Ii. Insufficient power supply

Because the USB hard drive also consumes a certain amount of power when working, if the power is directly obtained through the USB interface, it is likely that the power supply is insufficient. Therefore, almost all mobile hard disks are attached with a separate external power supply or a PS2 conversion interface powered by the keyboard. In this case, you only need to connect the external power supply in advance or connect the keyboard through The PS2 adapter, make sure that you have enough power for the mobile hard disk and try again. In this case, you should be able to use it normally. Note that we recommend that you ensure sufficient power supply before using the mobile hard disk. Otherwise, the hard disk may be damaged due to insufficient power supply.

Iii. USB cable extension failure

apart from the above two reasons, the USB interface type may not match, resulting in unavailability of the mobile hard disk. For example, the USB interface configured by the computer is 1.1 standard, and the purchased mobile hard disk is USB 2.0 standard interface, which requires that the connection line connecting the computer and the mobile hard disk must support the USB 2.0 standard. Because a high-speed mobile device is inserted into a low-speed hub, the device may not be properly installed, and some friends still use the USB flash drive while using the mobile hard drive, to facilitate the direct use of the USB 1.1 Standard cable attached to the USB 2.0, the USB standard mobile hard disk cannot be correctly identified. This fault can be solved by replacing the connection line with the USB 2.0 standard.
