- Q1.Why is the transfer rate far slower than 5Gbps as promoted?
- The USB 3.0 transfer rate of 5Gbps, with a theoretical transfer speed of 625MB/s, is about 10 times faster than of the mainstream USB 2.0 transfer rate of 480Mb/s, which has a theoretical transfer speed of 60 MB/s. Taking current usage conditions into consideration, the transfer speed can achieve about 3 times that of USB 2.0. The actual transfer speed depends on the specific environment the product is used in.
- Q2.The devices are not being identified by my computer when connected to the USB hub, but they are being identified when connected directly to the computer. Why is this happening?
- This problem may be the result of one of the following causes: a. Compatibility between the motherboard and system. Please try refreshing the BIOS in the motherboard. b. System or BIOS settings. The USB may be disabled in your BIOS or operating system. Please turn on the computer, press F2 or DEL to enter the BIOS interface, then select “Enable USB device”. c. Incorrect insertion or unplugging. Do not unplug the device when transferring data in order to avoid damaging the chipset. d. Improper driver installation. In “Device Manager”, go to “Other Devices” and select “Universal Serial Bus Controllers”. If there are any yellow questions or exclamation marks visible, uninstall the driver in “Device Manager”, and then restart your computer. The driver will be reinstalled automatically.
