Just bought a `subj` on ebay. Besides it is a pure SW MC8775, it exposes
the hp-specific vendorID and productID, is recognized as "hp hs2300 <something>"
and is not supported under windows by any SW 875U driver available. As a result, this card cannot be unlocked.
Below is a brief description of the possible workaround for 32-bit WinXP:
- get the _generic_ 875U windows driver from Sierra Wireless http://www.sierrawireless.com/support/show_support_and_downloads.aspx?id=20,6,1,1
and install it.
- plug the SW 875U dongle in and make sure it is not properly recognized
- copy contents of
\Program Files\Sierra Wireless Inc\3G Watcher\DriverInstaller\Drivers\WinXP\32bit
directory somewhere else
- edit the copy. following files should be edited the same way:
scrswi.inf
swnc8u.inf
swumdm00.inf
swuser00.inf
swuusb00.inf
using your favorite text editor duplicate every line containing substring "VID_1199&PID_6812"
and replace this substring with "VID_03F0&PID_1E1D" in a newly created line.
- perform standard XP procedure of driver upgrade:
(right_click on My Computer)->properties->hardware->device manager
- locate the HP hs2300 device, rightclick on it and choose 'update driver'
- perform an installation from specific location -- from the directory where modified .inf files reside.
Should ask some questions regarding the unsigned drivers...
- pull out the 875U dongle and plug it in again. Make sure that now it is recognized and working.
After all that I was able to unlock the card with no problem.
Hope this helps,
