Andy2k 0 Posted February 8, 2003 Is it possible to vary the 'fixed' amount of bandwidth that the system reserves for each USB port? I'm running a cable modem on USB, and also have a 4 USB port PCI card, and a MS keyboard with USB ports. The Modem is plugged into USB 1, and the keyboard port is plugged into USB 2. I have a USB mouse on the keyboard hub, and a ZIP drive (this gets swapped out with other devices sometimes) There will only be a printer on the 4 port card. I noticed that one of the USB ports (1 I think) has 20% of system bandwidth assigned to it, and all the others have 10%. Even when I only had the two ports by themselves, these percentages didn't change. Disabling a couple of the Ports on the PCI card didn't do anything to this either. Is there any way to reassign the resources so that the port with the Modem has a greater percentage of bandwidth reserved? I tried to connect the modem via an ethernet NIC, but the software that came with the modem sulked, and refused to reasign DHCP IP addresses for it, which is why I went back to USB. Am using Win XP home, with all service packs/updates. Athlon 1100, 512 MB RAM. Cable modem should be at 600K/s but usually only manages 200K. I have Norton Firewall and AV running, but disabling these doesn't seem to make a great difference to the speed. Any help appreciated. Share this post Link to post
