USB modem and USB controller?

I'm having a problem with both my USB modem and controller. Wehn the modem is on my FPS in GPL and Nascar 2k2 plummet to about 12 fps. When I turn off the modem, fps goes back to normal. This happens online and off. Does anybody know why? Is there a fix? I've taken my controller (TSW2Mod) of the USB and put it back to the gameport and everything is fine. I would like to use the USB controller though. I think it's more accurate. Both the modem and controller were plugged into the only 2 USB ports on my PC. Why the conflict? And why does it affect my FPS? Thanks, ZZ

USB is like a network. There is a limit to the total bandwidth available. For standard USB, it's about 12Mbit (roughly 1.5MByte) per second. That seems high, but some drivers may briefly hog the buss. Depending on the type of modem, there may be alot of traffic flowing through the buss, even when offline. Both of those ports are being run by one controller. The best fix may be to buy a second USB card. Spend a little extra and get a USB 2.0 card while you're at it and be ready for the new fast devices coming out. Putting devices on separate controllers is just like putting hard drives on different channels/controllers. -- If there is a no_junk in my address, please REMOVE it before replying!

Putting devices on separate controllers is just like >putting hard drives on different channels/controllers. The best fix is to get the modem totally off USB and onto an ethernet card. If you're out of slots and need to use USB, the second best way is to use a ethernet/USB converter (Linksys makes one), and use that. The USB drivers that come with RCA, Motorola and Com21 cable modems are flakey (these are the 3 I deal with). The USB converter uses it's own driver and you can use the ethernet port on the modem.

USB and WinModems are hard on the processor. There's only really one way around it. Get a true, external HARDWARE based modem. My all-time favorite is the USR Courier V.Everything, but most people find them a bit pricey. -Larry "ZZ Busch" <[email hidden]> wrote in message news:[email hidden]...

If that assumption was incorrect, please disregard. Tim
