I purchased a BT 4.0 mouse that can also be used az a USB wireless

not work. I wonder if it is because my HP laptop does not "understand"
the BT 4.0 standard or what? Could it be because the BT 4.0 mouse is not
downward compatible with possibly an older BT standard used by my Win7 PC?

I supposed you've checked to make sure that your Windows 7 machine
actually has Bluetooth, and that it's enabled? Bluetooth was not
common in laptops of that era; mine lacks it.


Broadcom 4328. (Could be combo 80211N Wifi plus some version of BT.
Like Bluetooth 2.1 EDR Enhanced Data Rate.)

I picked that up in Google using "tx-1410us dmesg", to
try to get a hardware dump.

It's probably a mini PCIe card of some sort with
two antennas on it. The BT is probably mixed in with
the 2.4GHz Wifi signal.

This is just a guess, because I can't find any further
information. The only other option would be dumpster
diving for drivers.
