Hi...
    i've written a driver for USB modem.it uses bulk transfers.I am facing a problem when i stress
it with UHCI host controller.when i run multuiple ftp sessions simultaneously(uploads and downloads),
after sometime data transfers stop and the modem ceases to be operational.i dont face this problem
in OHCI.am using linux kernel 2.4.2. also the original usb-uhci in 2.4.2 would not work,so i had backported
the usb-uhci from 2.4.18 to make it work on 2.4.2(just the data path).is there any known problem with urb queueing in uhci,or
is there any know problem that prevents uhci from being robust?thanx in advance.
regards
avinash
