Hi all.
This is a preliminary patch against 2.4.2 to uhci.c that puts the host
controller into global suspend when there are no devices attached. This
conserves power on mobile systems, and because suspending the host
controller ceases UHCI's incessant busmastering activity, it allows the CPU

Sorry for the long post - if this is inappropriate for the group please
tell me off, any followups that don't relate to wider USB development concerns
should probably just be mailed to me.
Who am I and what am I doing?
I'd like to add a few comments to this, but first
I want to apologize to Miles for some of my comments
yesterday. I didn't follow all of his statements,
but I agree with his conclusion.
I'd like to see this settled (solved) in a way that is
best for Linux, USB, and Linux-USB users, and develope

I've got the same error, either by using the libusb or ioctl() directly.
I ended by doing a kernel module ... and i'm currently doing it :-)

Hi folks,
I'm looking for how to modify the counter which determines how often

Actually, I have a problem of receiving the sent TDs. These TDs are sent to
device and get ACK as responce from device, I see them by using USB

Hi,
In the m8xxhci.c hci driver for the mpc one can select to use TIMER1 for
the SOF generator.
A interruopt handler, m8xxhci_timer_interrupt() is registered to handle
this interrupt and generate the SOF.
Why is it then that the timer is also exported to PA6?
Why is it the the USE_TIMER1_FOR_SOF

keyspan_pda and keyspan in the drivers/usb/serial directory both work
for the Keyspan PDA device. Long history,
