>Description:
When EHCI is enabled, data sent on the interrupt pipe by Prism and NET2280-based wireless devices is never received.
The problem doesn't only appear on my computer nor with my particular wireless device (Siemens Gigaset USB Adapter 54)
I also posted on the USB mailing list, see
http://lists.freebsd.org/pipermail/freebsd-usb/2005-January/000608.html
>How-To-Repeat:
Download the driver from http://yoshiyo.ath.cx/seb/prism54_freebsd.html
If using EHCI, the driver will never get the interrupt which occurs right after the firmware upload. If using UHCI, it will work.
