struggling to enable ethernet on BB (with a msc7830 usb-ethernet dongle)

I'm trying to connect a mcs7830 usb-ethernet device to BB for
networking but I'm unable to get an interface registered. I suspect
the following lines printed by ehci_hcd tell something about thr
problem. Apparently it's unable to enable "usbhost_48m_fck" as the log
suggests. But, i have no idea what the significance of that message is
and how to fix/work-around this.

Appreciate any insights.

I'm able to get the moschip driver to work without problems.
what is the kernel version that you are using?

Thanks for your response. I'm using 2.6.31-rc5. I think the problem
is being discussed extensively in a different thread named "USB EHCI
Problems". What is the version you are using? I'll probably just get
down to that version to get started.

hi

i was using 2.6.29-omap1 when i used the moschip-based usb ethernet dongle.

however, I think your problem is NOT related to the USB EHCI problem,
