Couple options off the top of my head: 1) Check your triggering/polarity for the ohci device. Are you sure the UIC is set correctly for this device? Is this something custom hanging off the ebc? 2) You have a bug in your custom ohci HCI driver which causes it to stall before device insertion. Verify whatever status register ohci has that it is still running (I dunno, only know uhci stuffs here). Regards, -- Matt Porter porter@cox.net This is Linux Country.
