Hi Lubomir,quoted
It actually times out on a 8688 present in GuruPlug with sd8688.bin (md5=7233401e9687f8c880da547beed4324e) firmware (that's present in linux-firmware tree), but the adapter works fine. For that firmware times out with libertas_uap [1] as well, though it succeeds with sd8688_ap.bin (md5=52cd8f8296b9a7e1d3835d57416256b2) that was originally shipped with GuruPlug. That firmware is not in linux-firmware tree and btmrvl driver might win the race programming the 8688 with sd8688.bin anyway.

Lubomir, any reply? Should I drop this one? -- John W. Linville Someday the world will need a hero, and you linville@tuxdriver.com might be all we have. Be ready.
