Will I need special software to run USB?
Current operating systems all support USB, operating systems that are no longer
supported by their makers may or may not support USB without modifications.
Many devices get all of the software support they need from the OS, but there
are some that will come with a floppy or CD with specialized drivers for
that particular device. Don't worry about getting the right software
because the OS's that support USB always know how to determine if anything
else is needed and they will help you get the software loaded so the
device works correctly. At one time there was some limited support for USB
on Windows 95, but that is no longer available.

Can I disable the "HI-SPEED USB Device plugged into
non-HI-SPEED port" notice in XP?
Windows XP and Windows Server 2003 create a pop-up notice when a Hi-Speed USB
2.0 device is plugged into a USB port that does not support Hi-Speed. To get
the fastest performance from the device, the user must click the notice and
follow the instructions on the screen.
| 1. Start Device Manager. To do so, click Start,
and then click Run. In the Open box, type devmgmt.msc, and then
click OK. |
| 2. In the Device Manager window, expand
the Universal Serial Bus controllers node. Look for a host controller
with the word "Universal" or "Open" in the title. If you find one, double-click
it. |
| 3. On the Advanced tab of the Properties
dialog box, check the Don't tell me about USB errors checkbox. |
Note
Following this procedure will disable all USB notices, not just "HI-SPEED USB
Device plugged into non-HI-SPEED port."
The best way to prevent this notice from appearing is by installing a USB 2.0
hub that is Hi-Speed certified or by purchasing a USB 2.0 EHCI peripheral
component interconnect (PCI) add-in card. You can then attach your Hi-Speed USB
2.0 device to these Hi-Speed enabled ports. Most systems sold since 2003
already have USB 2.0 Hi-Speed enabled ports.

Which USB class drivers support Selective Suspend in Windows XP
and Windows Server 2003?
| 1. Usbhub.sys. - This driver can selectively
suspend a root or external hub when no devices are attached to it or when all
devices attached to that hub can be selectively suspended. |
|
| 2. Hidusb.sys. - This driver can selectively
suspend a HID device. It is your responsibility to trigger remote wake
signaling on all device state changes. To enable Selective Suspend in the HID
stack, the registry value SelectiveSuspendEnabled must be
enabled for the specific VID+PID of the device. For examples, see Input.inf. |
|
| 3. Bthusb.sys. - This driver can selectively
suspend devices on computers running Windows XP SP2 and later. The driver
requires the Bluetooth radio to set the self-powered and remote wake bits in
the configuration descriptor. The driver selectively suspends the Bluetooth
radio when there are no active Bluetooth connections. |
|
| 4. Usbser.sys. - This driver can selectively
suspend when there are no active modem connections. |
|
If enough OEMs ask for it, Microsoft may consider supporting Selective Suspend
for additional class drivers. Work is also being investigated on future
hardware architectures (CPUs, chipsets, and the operating system) to mitigate
the problems.

Will I need special
software to run USB with other Operating Systems?
No, what you need is Windows 95B with USB Supplement, Windows 98, Windows 2000,
or MacOS 8.5 (found in iMac and G3 systems). The operating systems pretty
much cover the software side. If you got a USB device, either the
operating systems have the necessary drivers or the manufacturers ship with the
required software/drivers for the hardware

Which operating systems support USB 2.0?
Microsoft has released the official USB 2.0 Driver for Windows XP and Windows
2000. The version is 5.1.2600. The software is available on-line at Windows
Update website. (If you don't have a USB 2.0 card installed in your system,
Windows Update won't list the USB 2.0 driver as an update.)
The software company is still considering USB 2.0 support for Windows ME, but
it already has decided not to bring USB 2.0 to Windows 98 and Windows 98 SE. If
you have Windows 98, you will have to rely on 3rd party USB 2.0 support from
USB card manufacturer.
As for Mac users, Orange Micro. and KeySpan are providing USB 2.0 for MacOS X
exclusively.
