Insufficient USB bandwidth

Azza · 19 Mar 2006 at 13:45

The past week or so, every time i try and connect to the internet i get a warning message appearing saying that i have insufficient USB bandwidth, and that i should close all programs, take out all other USB devices and plug the modem back in.

The only USB devices that are plugged into my pc are the printer and my broadband modem. I can resolve the issue by restarting the pc 3 or more times in a row and then it seems to be fine, but after a wihle it disconnects agian.

Has anybody ever had this type of warning and does any body know what the cause of it could be?

SiSoft Sandra says that it is USB1.0, it also says thatt he speed is at full(12mbps)

try juggling the ports on your pc that the devices are plugged into.

i just knew someone would post that. why? it's probably just a configuration problem that can easily be sorted out. i've been on broadband for about 3 years now with the same usb bt voyager modem and it hasn't missed a beat. it's worked fine on loads of pcs

p2 233 intel chipset of somesort (connection used to crap out when burning cds but that was a cpu problem i think

)
xp2600, sis chipset
xp2500, nforce2 chipset
and now an intel 875p chipset

Because USB modems are riddled with these issues (including reduced throughput with Max), and ethernet isn't?
Fix the bandwidth issue too.

ok fair enough. that's something i may have to look into myself. i wasn't aware of that.

but the OP has just 1mb download/synced at 2mb at the mo. i'm sure it will work if setup correctly.

Possibly, but USB modems are the source of a hell of a lot of hassle - it's quite often easier (and not fantastically expensive) just to replace it with an ethernet device (mostly a router).

Shoving the modem on a port that has a separate controller to your other kit might fix it.
