I was told that if i have xp SP2 my 1.1 usb ports would be upgraded to 2.0, but they wont upgrade. Is this a hardware problem, if not how can i get it to work? And there arent any ? marks or ! marks under the Device Manager.

Good point from . For clarity and next steps for , here is a short, practical checklist to diagnose whether the ports can be made to run at USB 2.0 speeds and what to do if they cannot.

Open Device Manager (Start -> Run -> devmgmt.msc) and expand "Universal Serial Bus controllers." An entry that mentions "Enhanced" or "EHCI" (or explicitly says USB 2.0) means the host controller supports high speed. If you only see entries for UHCI/OHCI or plain "Universal Host Controller" without "Enhanced," the onboard controller is almost certainly USB 1.1. You can also run msinfo32 (System Information) -> Components -> USB to view connected hubs and device speeds.

If the controller supports EHCI but devices still run slowly: install the chipset/USB drivers supplied by the PC or motherboard maker, and check BIOS for any USB 2.0/EHCI enable/disable option. If the motherboard lacks EHCI/USB 2.0 support, the only practical fixes are an add-in PCI USB 2.0 card (comes with drivers for XP) or a motherboard upgrade. When testing, use a known USB 2.0 device and a good cable, and plug directly into the motherboard rear ports (front-panel headers or unpowered hubs can force 1.1 speeds).

Simple speed checks help confirm results: USB 1.1 tops out at about 12 Mbps (roughly 1.5 MB/s), while USB 2.0 devices often achieve tens of MB/s in real use. Following the Device Manager/MSInfo checks above will show whether the limitation is hardware or just a missing driver.

I think someone fibbed to you ,to the best of my knowlage USB is hardware and a software upgrade isn't goining to change that .
