Hi,
Several Gentoo users are reporting that usb-storage devices no longer
work on 2.6.16 with unpowered hubs.
Here's some logs:
hub 2-2:1.0: state 7 ports 3 chg 0000 evt 0002
hub 2-2:1.0: port 1, status 0101, change 0001, 12 Mb/s
hub 2-2:1.0: debounce: port 1: total 100ms stable 100ms status 0x101
usb 2-2.1: new full speed USB device using uhci_hcd and address 7
usb 2-2.1: not running at top speed; connect to a high speed hub
usb 2-2.1: default language 0x0409
usb 2-2.1: new device strings: Mfr=1, Product=2, SerialNumber=3
usb 2-2.1: Product: Store 'n' Go
usb 2-2.1: Manufacturer: Verbatim
usb 2-2.1: SerialNumber: 0CD177515381390D
usb 2-2.1: uevent
usb 2-2.1: device is bus-powered
usb 2-2.1: no configuration chosen from 1 choice
drivers/usb/core/inode.c: creating file '007'
hub 2-2:1.0: 100mA power budget left
hub 2-2:1.0: state 7 ports 3 chg 0000 evt 0002
This device works in the same hub in 2.6.15, and works when plugged
directly into a USB port on both 2.6.15 and 2.6.16. The problem has been
reproduced on 2.6.17-rc4.
I'm working on getting a complete report filed at the kernel bugzilla,
but thought I would throw some attention to it here first, is it a known
issue?
The Gentoo bug report is at
https://bugs.gentoo.org/show_bug.cgi?id=132721
but it's a bit of a mess..
