i.MX53 QSB, Linux 3.7 and USB

nodan — Fri, 28 Dec 2012 14:14:42 GMT

Hi,

I'm running a Linux 3.7 kernel on an i.MX53 QSB. However, it looks like USB is not working properly. In /proc/devices I see:

# grep -i usb /proc/devices
180 usb

189 usb_device

but lsusb fails:

# lsusb
unable to initialize libusb: -99

Actually I want to use a USB Wifi dongle. Has anybody done that with the QSB?

Regards,

Kai

If you look at arch/arm/boot/dts/imx53-qsb.dts you will see that USB support is not in place yet.

You can look at arch/arm/boot/dts/imx6q-sabrelite.dts as this board has USB host support.

Then you can try to send your patch to linux-arm-kernel mailing list and we can discuss from there.

Again, thanks.

I'll have a look but I'm not sure yet if I'll try to use USB or rather settle for an external wifi access point and use the LAN interface.
