Icon speedy deletion.png Warning: With current versions of ReactOS, USB support is NOT advanced enough to successfully work with USB flash-drives, web-cameras and etc. Please mind that system may crash due problem caused by USB-device. Please, if possible, avoid using USB devices together with ReactOS, unless you know what you are doing.

The page USB is a short article on something that should have a lot more information written on it.
If you know anything else about it, you are STRONGLY encouraged to add the information in. If you are unsure of proper formatting or style, add it to the talk page or this page itself as you think best and others will help.

Additional notes

  • To achieve successfull Live USB boot, it is enough to merge all patches that are marked as Required.
  • Before merging new UHCI and EHCI drivers, "Correct size adressing for PA" patches should be merged.
  • Patch #8 with black list of devices is required to boot successfully on some machines, until the support for Isochronous Transfers would be implemented.
