Howdy, I've looked through the archives and couldn't find an answer to my questions, so....
I have an embedded system where I use a hotplug script to automount a USB stick. Sometimes it fails and the error I see is (via dmesg): hub.c: new USB device 00:0e.0-1, assigned address 2 scsi0 : SCSI emulation for USB Mass Storage devices Vendor: SanDisk Model: U3 Cruzer Micro Rev: 3.21 Type: Direct-Access ANSI SCSI revision: 02 usb_control/bulk_msg: timeout host/usb-ohci.c: unlink URB timeout The script will not run at this point as the stick doesn't appear to be mounted. It's a linux 2.4.29 kernel (Debian distro) with basic USB support (snip of config file below). The hardware we have for the USB is a USB 1.1 port. The vendor for the USB stick (as shown above) is SanDisk - U3 Cruzer Micro model. Some of their sticks work in this system, others don't (same exact model sticks). I've had more and more of these issues over the past year with this system and I'm wondering if it's the fact that USB 1.1 (which this system is using) is not really supported by USB 2.0 sticks (though the manufacturer says it is). My question's are - can anyone tell me more about this URB timeout and what it's caused by? Could the USB stick be misbehaving or the kernel simply not up to date enough for these 2.0 sticks? I cannot easily upgrade the kernel - so I'd like to try to work with what's there... Thanks for any help/advice on this. If this isn't the right forum, any suggestions on which one might be?
