Hello everyone!,
How to tell if my computer’s Mini PCIe slot is a true full Mini PCIe that implements USB embedded lines?
My laptop is a Sony Vaio CR21S. I have upgraded the built-in WIFI (Intel 3945) for a better one (Atheros AR5B225). To use the Atheros in a PCIe adapter, it needs to have a USB connector on that adapter card in order for Bluetooth to work.
Unfortunately only the PCIe part works for me, that is, the WIFI. Bluetooth is not detected at all. I tried both Windows and Linux. Only the very old built-in Bluetooth 2.0 that I haven’t removed was detected.
How would I know what the problem is? I think it is because my mini PCIe does not implement USB. In that case, I would like to know if there are mini PCIe combo cards WIFI + Bluetooth where the BT could work on a mini PCIe slot without embedded USB lines.
Thanks you very much in advance.
