I have some mini pcie wireless cards I want to use with my laptop. I ordered one such device from amazon, but it was a sham, there was litterly no components on the PCB, there is no way I could have worked. What USB to mini PCIE device do you recommend? Operational with Linux would be a requirement.
You're not going to find one.
USB and PCIe are two very different technologies supported by the PCH (Platform Controller Hub) in the chipset of your PC/Server.
The I/O portion of the PCH supplies both PCIe and USB interfaces to the system. However, PCIe being an expansion bus allows you add additional USB controllers to the system; the USB interface doesn't allow you to add PCIe controllers.
You need to us a USB WiFi Adapter compatible with your flavor of Unix.
