I would like to confirm this bug. I am experiencing similar problems on Ubuntu karmic with the latest updates and kernel 2.6.30.1 compiled on my own from kernel.org. I have also tried the provided 2.6.31-2-generic kernel, as well as the current Jaunty kernel (2.6.28-11-generic), but the results were the same:
Basically, I get my external USB drive detected, but I don't get the /dev files generated and therefore I cannot access my drive. There are many "device descriptor read/64, error"s and "device not accepting address %NUMBER%" errors followed by "unable to enumerate USB device on port 1" errors in dmesg: [ 87.256073] usb 1-1: new high speed USB device using ehci_hcd and address 5 [ 87.389479] usb 1-1: New USB device found, idVendor=152d, idProduct=2329 [ 87.389489] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=5 [ 87.389496] usb 1-1: Product: USB to ATA/ATAPI Bridge [ 87.389502] usb 1-1: Manufacturer: JMicron [ 87.389506] usb 1-1: SerialNumber: 13D107568FFF [ 87.389712] usb 1-1: configuration #1 chosen from 1 choice [ 87.650345] Initializing USB Mass Storage driver...

I could not think of anything else than something was messed up in karmic koala, which prevents USB drives from working correctly. I just wonder what it is ... and more importantly, how to make it working again. -- Koala: External SATA->USB Drive no longer being identified properly https://bugs.launchpad.net/bugs/387161 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
