Dear list, dear Linux USB Developers, on the first sight my question seems to be the same like thousands out there which normally are "damaged device" or "broken cabeling", but I promise my case is somewhat special. I have a USB Flash drive (Corsair Voyager 8GB) which long time worked fine on 3 different PC running Ubuntu (first 8.04, now 8.10). Today I plugged the device into my laptop, filled it with data and later on gave the device to a colleague who plugged it into his Ubuntu 8.10. The device wasn't recognised (error messages and debug stuff follows below). Since then it doesn't work anymore on my laptop where I filled it this morning, nor on any other Linux machine I tried it. One would say, okay, the stick is now dead, got too much voltage or such, simple as that. But interestingly on Windows it still works fine. 2 of the 3 PCs I have in reach are dual boot and as soon as I boot into windows, the stick works like a charm! So somehow the one Ubuntu system changed something on the stick which broke functionality with linux only. Bad thing is that the mass storage driver doesn't even initialize the block device, so I am not able to e.g. fill the device with zeros to wipe it. All I can try i need to do on Windows. There I tried deleting the partition on it and created a fresh FAT32 partition, but to no avail. Windows: fine, Linux: nothing. I tried with ehci and ohci (by unloading ehci), but no difference (beside mentioning the actively used driver in the error messages), I tried booting with acpi=noirq or acpi=off and tried to give usbcore module the option "old_scheme_first=y". No change at all. Okay, now the dirty details about my main system where I did all research: Ubuntu 8.10 running on an Acer Extensa 5220 (Celeron M540 on an Intel GM965 chipset) While pluggin in the usb stick I have following dmesg output: [ 3600.916141] usb 4-1: new full speed USB device using uhci_hcd and address 11 [ 3616.029425] usb 4-1: device descriptor read/64, error -110 [ 3631.244060] usb 4-1: device descriptor read/64, error -110 [ 3631.460053] usb 4-1: new full speed USB device using uhci_hcd and address 12 [ 3646.572555] usb 4-1: device descriptor read/64, error -110 [ 3661.788051] usb 4-1: device descriptor read/64, error -110 [ 3662.004060] usb 4-1: new full speed USB device using uhci_hcd and address 13 [ 3672.412680] usb 4-1: device not accepting address 13, error -110 [ 3672.524051] usb 4-1: new full speed USB device using uhci_hcd and address 14 [ 3682.932043] usb 4-1: device not accepting address 14, error -110 [ 3682.932575] hub 4-0:1.0: unable to enumerate USB device on port 1 and following entries in messages: Feb 2 19:48:07 azure kernel: [ 435.092045] usb 7-1: new high speed USB device using ehci_hcd and address 2 Feb 2 19:48:07 azure kernel: [ 435.259426] usb 7-1: configuration #1 chosen from 1 choice Feb 2 19:48:08 azure kernel: [ 435.386281] usbcore: registered new interface driver libusual Feb 2 19:48:08 azure kernel: [ 435.417478] Initializing USB Mass Storage driver...

Can anybody see any cause in all those infos? Can I provide more infos on any detail? If anyone knows some more creative ways to wipe any false informations on the device which may cause this, it would help as well! Thank you all and best regards, Daniel
