We find that USB modems use more CPU cycles than even Winmodems, generally. I consider USB modems to be a bad idea, poorly executed.

Know what I would do? Get a faster CPU!

: Hi

: Been having allot of problems with a Asuscom USB ISDN modem. Mostly because of extremely poor drivers from the develeopers Asus (also sold as Dynalink and Askey). Bugfixes and new drivers came out almost daily for more than a year - lying in the box for the most part of a year waiting for a fix for the constant line drops).

: Finally updated to WinXP and seems allot more stable, but consumes HIGH (80-90%) CPU when using the onboard Via controller. Have a USB Creative Webcam Go (works ok) and a USB HP Scanner (Great scanner).

: I have no idea how to fix the resource problem - ended up getting a powered hub (no difference - still high CPU - webcam works better off it though).

: Purchased a CMD PCI USB card (supported native by XP) and running the modem off it now. It now consumes 20%-30% resources (much better but almost intollerable when using the Net).

: I've tested the modem on Intel based chipsets and it seems to function correctly - It does not consume any resources when plugged in Win2k/Me on my machine - only in WinXP.

: Could there be some problem with the USB minport interface with this modem in WinXP?

: The manufacturers blames my PC - but all my other USB devices works great -

: Any help is much welcome.
