Issue with serial devices and usb power hub

Unread postby thohtdelta » Fri Aug 03, 2018 3:17 am

Hi,
I am using odroid xu4 with dietpi OS v6.7. I have connected Panda wireless wifi adapter and bu-353s4 GPS through transcend USB 3.0 power hub to xu4. I am getting an error in dmesg as follows:

Code: Select all
rt2x00usb_vendor_request: error -vendor request 0x07 failed for offset 0x10c
with error -110
rt2800usb_watchdog:warning -TX HW queue o timed out, invole forced kick
rt2x00usb_regbusy_read: Error - Indirect register access failed:
offset=0x0000101c, value=0xc0936sec


Since gps is also connected through same transcend usb3.0 hub, I checked gpsd service status It displayed the error as follows:

Code: Select all
gpsd:ERROR: device open of /dev/ttyUSB0 failed: No such file or directory -
retrying read only
gpsd:ERROR: read only device open of /dev/ttyUSB0 failed: No such file or
directory
gpsd:ERROR: /dev/ttyUSB0: device activation failed:
gpsd:ERROR: /dev/ttyUSB0: activation failed, freeing device


What might be the reason for these errors?
Is that problem with USB power hub or something else?

Check "lsusb" and "lsusb -t" outputs first.

Which Kernel version do you use on the DietPi?
