i use one smargo smartreader v2, but not in FTDI mode and works 100%.
if you use oscam+smartreaderv2, you can use it in libusb mode, its even beter than fdti, maybe you could try.
My problem is that it's not being detected by the kernel. I have no devices listed for the smargo if I issue a lsusb command.

How do I not use FTDI?
