* This driver has been tested SUCCESSFULLY with the following drivers :
* o usb-uhci-hcd (For Intel/Via USB controllers)
* o uhci-hcd (Alternate/JE driver for Intel/Via USB controllers)
+ * o ohci-hcd (For other USB controllers)
*
* This driver has NOT been tested with the following drivers :
* o ehci-hcd (USB 2.0 controllers)
*
- * This driver DOESN'T SEEM TO WORK with the following drivers :
- * o ohci-hcd (For other USB controllers)
- * The first outgoing URB never calls its completion/failure callback.
- *
* Note that all HCD drivers do USB_ZERO_PACKET and timeout properly,
* so we don't have to worry about that anymore.
* One common problem is the failure to set the address on the dongle,
