Hello I am utilizing two pMDDL2450 microhards. I have confirmed they are talking within the Microhard web browser. They both get recognized by my computer but when I go to plug the 2450 in the USB carrier board into my S21 it is not detected. Is there a driver I need to download to interface with my phone?

@Brandon-Wightman I believe your phone would need a lan7500 driver
