usb 1-5.4: reset high speed USB device using ehci_hcd and address 3
hello,
i've had big problems with my via onboard USB 2.0 controller, it gave
thousands of messages like the following to the console:
usb 1-5.4: reset high speed USB device using ehci_hcd and address 3
after someone told me, that the via USB 2.0 controllers are known to be
bad quality, i bought an Adaptec USB 2.0 controller with a nec chipset.
lspci gives the following:
0000:00:08.0 USB Controller: NEC Corporation USB (rev 43)
0000:00:08.1 USB Controller: NEC Corporation USB (rev 43)
0000:00:08.2 USB Controller: NEC Corporation USB 2.0 (rev 04)
currently, i've only three USB devices conntected to the controller:
- an external USB 2.0 400GB harddisk (Seagate)
- a USB 2.0 multi- cardreader which is a HUB too
- and a digital camera (USB 1.0), connected to the cardreader (Minolta)
i cannot say anything about the quality of the new Adaptec USB
controller yet, as i've just installed it yesterday, but i hope that at
least the serious read-/write- errors [that happened with the via
controller] will not occur again.
but unfortunately the messages to the console didn't disappear with the
new controller. i get the following message inregularely, but the
average may be something like 3 minutes:
usb 1-5.4: reset high speed USB device using ehci_hcd and address 3
and another log message is printed to the console inregularely, but
maybe every hour or so:
ehci_hcd 0000:00:08.2: qh ffff81001f00aa00 (#00) state 4
unfortunately these messages mess up fullscreen console apps like mutt,
irssi, vim etc. but that's not the biggest problem. i could configure
syslog-ng to just print them to kern.log and not to the current console.
but what i really want is to know why these messages occur, and how i
fix that. do you have any suggestions here?
greetings
jonas
