Hi,
I get similar babble errors every now and then with a usb keyboard. Also,
unplugging and replugging the keyboard almost always result in babble error.
The logs are attached, I will try to disable the DMA and recompile the kernel.
For connecting keyboards only, disabling the DMA should not have a huge side
effect anyhow, right?
BR,
Marcell

Hi,
[...]
Interesting, I've never seen this error. I'm suspecting there are some
alignment issues going on which then cause USB babble errors.
Could you please increase the musb driver debug level by doing:
# echo 8 > /proc/sysrq-trigger
# echo D3 > /proc/driver/musb_hdrc
And then post the dmesg after plugging in your device.
After that you may want to try to recompile the kernel and leave out
musb DMA support by setting CONFIG_USB_INVENTRA_FIFO in .config. If that
works let me know.
Also please post info on the device you're connecting to the USB port,
such as device model and maybe the relevant part of lsusb -v on your
Linux PC.
Regards,
Tony
