Public bug reported:
I'm on Ubuntu 7.10 on an old Pentium 4 1.4GB machine. I have two USB devices
(on the only two slow sockets the came with the motherboard): an ADSL modem
(Huawei SmartAX 810) and a Microsoft IntelliMouse. When I tried to configure
the modem (with the firmware taken from
http://eagle-usb.org/ueagle-atm/non-free/), the mouse stopped working. If I
unplug the modem, the mouse still works OK. In Windows XP, mouse and modem live
together with no quarrels. Back to Ubuntu, the modem seems to work alright,
connecting to internet and all. In dmesg, I see several times a line saying
"reset low speed USB device". The keyboard (PS/2) acts erraticly in X (but OK
in the console), repeating unexpectedly several times a key, but I don't know
whether it's related to this problem.
Looked for this problem in other bug reports. Didn't find anything that closely
matches my behaviour. Tried with no results:
1) Uninstall plptools (it was never installed in the first place)
2) rmmod acpi_sbs, i2c_acpi_ec (they were never insmod'ed)
3) By one or combined kernel parameters:
3.1) ec_intr=0
3.2) noapic
3.3) acpi=noirq
3.4) notsc
3.5) i8042.nomux=1
3.6) acpi=off
4) Switched the devices in their sockets
5) With only one of them plugged, the other works OK.
6) Unplugged and plug again the mouse (sometimes it gets detected, but still
doesn't work).
If it's any other information I can provide to solve this, I'll be happy to
oblige. I wanted to switch from XP to Linux, but with this problem, the box is
completely useless.
Thank you very much in advance.
