| |
Hi,
I'm part of EciAdsl USB ADSL modem driver developers (http://eciadsl.flashtux.org) I installed 2.6.7 kernel and I have some problems: since I upload anything at max speed (15 kb/sec for me), I'm disconnected after 2-5 sec with this USB error in /var/log/messages: Jun 19 11:13:18 photon kernel: usb 1-2: bulk timeout on ep2out Jun 19 11:13:18 photon kernel: usb 1-2: usbfs: USBDEVFS_BULK failed ep 0x2 len 1984 ret -110 No problem when I download sth.
I've tested with 2 machines (same problem), with these USB chipsets: machine 1: 0000:00:07.2 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 10) machine 2: 0000:00:1d.0 USB Controller: Intel Corp. 82801DB (ICH4) USB UHCI #1 (rev 03)
I tested with noapic option, same usb crash. Many other people have same problem, maybe not for each upload, but lot of disconnections with same error in logs..
Finally, I have no problem with 2.6.6 kernel or any older kernel (2.6 or 2.4): connection is very stable.
Feel free to ask me more for testing. Thanks for any help.
I've not subscribed to LKML, so please CC me for any answer.
