Server for universal serial bus (USB)
|You must be root to start this server.|
io-usb [-d dll [opts] ] [-n name] [-P]... [-V] [-v]
The io-usb server contains USB protocols and communicates with clients (class drivers). The USB stack is a server/dll interface which the server uses to load the DLLs that manage the USB chips. You can load drivers when you start io-usb by specifying the -d command-line option.
|You can start more than one driver by using multiple -d command-line options.|
Once io-usb has started, you can dynamically load and unload modules using the mount and umount commands.
The io-usb controller uses the LD_LIBRARY_PATH environment variable when searching for the shared objects. If LD_LIBRARY_PATH is not set, or the shared object in question isn't in one of its directories, or you want to override the default, specify the full path in the mount command.
For example, to mount the EHCI (high speed) USB driver:
mount -Tio-usb devu-ehci.so /dev/io-usb/io-usb
to mount the OHCI (full/low speed) USB driver:
mount -Tio-usb devu-ohci.so /dev/io-usb/io-usb
to mount the UHCI (full/low speed) USB driver:
mount -Tio-usb devu-uhci.so /dev/io-usb/io-usb
Start the USB 2.0 stack and USB drivers:
io-usb -dehci -dohci -duhci
or use this sequence of commands to do the same thing:
io-usb & mount -T io-usb devh-ehci.so /dev/io-usb/io-usb mount -T io-usb devh-ohci.so /dev/io-usb/io-usb mount -T io-usb devu-uhci.so /dev/io-usb/io-usb
Unload a module:
devu-ehci.so, devu-ohci.so, devu-uhci.so, mount, umount
