* The U132 adapter is a USB to CardBus adapter specifically designed

|

* The U132 adapter will *NOT *work with PC cards that do not contain

* an OHCI controller. A simple way to test whether a PC card has an
|

* OHCI controller as an interface is to insert the PC card directly
|
||||
* into a laptop(or desktop) with a CardBus slot and if "lspci" shows
|

* a new USB controller and "lsusb -v" shows a new OHCI Host Controller
|

* PC card.(you also need the specific client driver for the PC card)

* Please inform the Author and Maintainer about any PC cards that
