PROBLEM: ======== ehci-hcd storage device resets during I/O with 2.6.12.1 (vanilla) DESCRIPTION: ============I encountered problems with memory devices (flashdisks, memory-card readers) connected to USB 2.0 PCI card. After connecting the device to the USB port it is found by system properly and assigned to /dev/sd? files. I can mount them and read from/write to them, but after a while the device is reset and reading/writing stops and error message appears (Can't read file xxx). Duration of this while differs for every attempt. After trying hardware (removing other PCI cards, moving USB PCI card to other PCI slots, disabling motherboard's built-in USB) and software (mostly experiments with loading and unloading relating modules) changes I found the problem is in ehci-hcd module. After unloading it the memory device works without reset, but only like USB 1.1 device.
Changelog of kernel 2.6.12 says there is a patch for EHCI ([PATCH] spin longer for ehci port reset completion by David Brownell), so I compiled and used it (exactly i used 2.6.12.1 from kernel.org): Device is properly recognized after connecting to the USB port; I mount it and start reading data from it. After a random-long while the transfer stops, but after next while it runs again. In result the reading is much slower than with UHCI. After few measuring attempts the copying of about 120 MB from the device the process hanged up - there are messages about resetting the device, but copying process didn't end by error (I used drag and drop copying with KDE's Konqueror and the progress is 82% last two hours).
Beside this I also use CDMA modem (Gtran GPC-6420 - this model is AFAIK specific for Czech republic) connected to USB (uses cdc-acm module) and there are no issues with it, no matter if it is connected to 2.0 PCI card or to integrated 1.1 USB port or disconnected at all.
