USB: don't allocate dma pools for PIO HCDs
hcd_buffer_alloc() and hcd_buffer_free() have a similar dma_mask
check and revert to kmalloc()/kfree(), but hcd_buffer_create()
doesn't check dma_mask and allocates unused dma pools.

Hi,
I am new to Linux USB Subsystem. I have to develop driver for downloadign

Hi,
I am doing a USB Host driver for my h/w on an arm board on linux. My
question is regarding interrupt urbs. Are these things periodic?

It's hard to answer your question, partly because you haven't expl

Hello!
I would like to start a C-Server for my USB-Device every time it is plugged
on. I tried it using udev but this did not work.
I used as example to call the shell which starts eclipse:

"usb/Moeller_HID_GW", PROGRAM="/usr/bin/eclips
