Mandriva Linux can handle a large number of hardware devices, and the list is far too long to be quoted exhaustively. You may consult an up-to-date list of supported hardware on the Mandriva Linux Hardware Database web site.
Support for USB 1.x and USB 2.0 is now extensive. Most peripherals are fully supported. You can obtain the list of supported hardware on the Linux-USB device overview site. Relevant information can also be found on the Linux USB web site.
