Any clues or suggestions on how to solve the following would be appreciated: The device is a Digi Edgeport/8 USB/serial adapter, using the io_ti driver with CentOS 5.4, kernel 2.6.18 The device works perfectly on a Dell GX280 (Pentium 4, ICH6 chipset, 2.6.18-164.15.1.el5). However, on a Dell Poweredge 2900 (Core 2 Quad, 631xESB/632xESB/3100 Chipset, 2.6.18-164.15.1.el5PAE) I get: "edgeport_ti_2 ttyUSB0: edge_open - usb_submit_urb failed with value -22" Thanks for any help.
