Re: Usb device detection in grub

[Arindam Khan]

Hi,

  Noted. But whenever I am running "insmod ohci" or other host controller (ehci or uhci) in grub command line and then "usb", I get always "(hd0, mdos1) not found error" even for serial modem device.

  Please help.

with regards,

Arindam

Hi,

   I am working on a custom STM32 board and have configured the board's USB OTG as a serial modem device. In Linux, it is getting detected as a "/dev/ttyACM" and all read and write is working fine. However, when I load the "usbtest" module of grub and run it with the "usb" command, it does not show any USB devices. Is it possible to iterate over all usb devices attached in a machine in GRUB? 

kindly help.
