Hi David,
I had no idea that there was different types of USB controllers. I
will check but I am sure my motherboard only has the usual host
controllers. So I didn't check out the whole NSLU2 documentation yet
but do you mean that the USB Gadget support in the kernel allows a
work around the type of controller I have?
Many thanks,
Thomas
