I work with IGEPv2 board for our product box solution, connected to a 3G modem using USB1 type A or USB2 OTG.
The USB of the modem is specified to work in high speed mode (480Mb/s).
In IGEPv2 USB debug logs, i can notice that speed is changing when some errors occur with message like this:
hub 1-0:1.0: port 1, status 0100, change 0001, 12 Mb/s
And later come back to high speed mode:
hub 1-0:1.0: port 1, status 0501, change 0001, 480 Mb/s
Would you know Linux commands to force USB driver always using high speed mode please? (even if errors occur)
I would like the USB speed to never change, and remaining in High Speed mode.
Thanks in advance for your help,
