Hello,
I have this DH87RL-board for a few months now. I had problems with USB right from the start.
At first I thought that the cause of the problems was the device itself or the OS but now I'm quite confident that it's the board.
I'm running Kubuntu 14.4 and Windows 7 Pro. Problems occur under both OSes.
This is what I observe:
- I'm using USB keyboard and mouse and both work well -- using any of the connectors (front, rear, USB2, USB3) under both OSes.
- In the boot loader (standard linux boot loader) the keyboard is only working when I select "USB legacy mode" in the BIOS. I find that
quite strange as on the other hand I'm able to enter the BIOS using F2 (prior to the boot loader) in any case.
- My USB2-Stick (Kingston) is also working under all conditions.
- But other devices don't work -- for example my smartphone. The strange thing is that it sometimes works and sometimes not.
My printer/scanner on the other hand never works.
In case my smartphone doesn't work I see messages like the following in the Linux logs:
usb 3-9: new high-speed USB device number 10 using xhci_hcd
usb 3-9: Device not responding to set address.
usb 3-9: Device not responding to set address.
usb 3-9: device not accepting address 10, error -71
usb 3-9: new high-speed USB device number 12 using xhci_hcd
usb 3-9: Device not responding to set address.
usb 3-9: Device not responding to set address.
usb 3-9: device not accepting address 12, error -71
The cause of the problems is not in the USB devices as all devices work well on different computers using different OSes.
My specs:
AA-Number: AAG74240-402
Serial: BQRL331000SC
Version: RLH8710H.86A
I also upgraded to the recent BIOS (0326) but to no avail.
Hope someone can help.
Kind regards,
Christian
