I tried doing this, but the copy_to_user functions did not work then. They only work when I wait for the bulk_isr() to resubmit 1 URB at a time. I must be doing something wrong in the bulk_isr function (I basically just copy_to_user in this function), even with the QUEUE_BULK flag. Do I need to use the QUEUE_BULK flag? The queueing definately works in the latest stable version in MDK 9.2? > > And the reads shouldn't block while you're waiting for the > writes to complete ... So, basically make threads for both read and write? thanks Ted -- Ted Huntington Programmer Analyst I Main Library University of California, Irvine PO Box 19557 Irvine, CA 92623-9557 emesgs: [EMAIL PROTECTED] web page: http://business.lib.uci.edu/webpages/ted.htm 8:00a-12:00p Business Office (949) 824-8926 1:00p-5:00p Multimedia Resource Center (949) 824-1674 "Stop violence, teach science." ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
