| |
Hi,
I use a tool called hidmon to control the parameters of my LCD in shell scripts. I just had the case where this tool didn't work after suspend to RAM. I just got this error message:
hid_force_open failed with return code 13
The kernel log contains lines like this:
usb 1-1.3: usbfs: USBDEVFS_CONTROL failed cmd hidmon rqt 129 rq 6 len 9 ret -110
Unplugging and replugging the USB cable of the LCD didn't work. However, after a further suspend/resume cycle it works.
This is Linux 2.6.25-rc5. The behaviour is not repoducible, though. However, I just mention it for the case that this might ring a bell somewhere.
Regards, Tino
