Model: HP iPaq h5450 using Windows CE 2002
Problem: Message saying "the fingerprint reader failed to turn on due to insufficient driver memory available. You must perform a normal reset to use the fingerprint reader"
I do a normal reset and get the same message.
I do a hard reset, get to the 'align screen', then get the message again.
I take the battery out, leave it out overnight, and get the same result as a hard reset.
The hard reset is supposed to clear the memory, which it does (mostly), but it didn't eliminate the password/fingerprint requirement for me to log in. Since the fingerprint is my normal authentication method, and it doesn't work, I am locked out of the device.
When I try to access from activsync 3.7.1, I type the password that worked earlier and now it doesn't work.
I can't use HP support, since I'm out of warranty.
Let me know what you think or if you need more info.
