Hello, I have two laptops: - Lenovo X201 running Debian unstable, kernel 3.2.0-4-amd64 (also has 3.2.0-3-amd64 and 2.6.32-5-amd64) - Thinkpad X31 running an out-of-date Debian unstable, kernel 3.2.0-2-486 (haven't turned this one on in a while and consequently haven't updated packages)
Also have a 600GB LaCie external hard disk. When I plug the disk's usb cable into the X201 (up-to-date), the laptop notices nothing. The disk does start doing stuff, but no acknowledgment in dmesg or lsusb. Plugged the disk in to a Mac machine, which recognized it. On the mac, I reformatted it to vfat. Plugged it into the X201, still no response on the computer. I plugged the same harddrive into my old X31 running the old kernel and it recognized it as /dev/sdb1. I ran badblocks (for hours) and it said everything was fine. I plugged it into the X201 and still nothing. A further troubleshooting attempt, I noticed that on the X31, uhci-hcd was in the list of loaded kernel modules. It wasn't on the X201. I modprobed it, but still nothing. I rebooted the X201 to an old kernel (2.6.32-5-amd64), but still nothing. Just to try again, I restarted X31, plugged in the harddrive and it was recognized right away. I noticed that the X31 list of modules had one called uas in the usb system. The module uas isn't in 3.2.0-4, but is in 3.2.0-3, so I rebooted the X201 into kernel 3.2.0-3, modprobed uas (and uhci-hcd, for good measure), but still not recognizing the disk. Last, all this time, the X201 was in a docking station. I removed it, rebooted and tried again, but still nothing from the X201 upon connecting the harddrive. Any thoughts on what the problem is or how I can diagnose it? Thanks for your time!
