I have been working on a CF19 with some USB issues. Issues such as, they don't work.
In my experimenting, I tried a PCMCIA to USB adapter. I will only plug a USB stick into these as they do not supply enough current for anything else.
I discovered that the CF19 WILL boot from a USB stick plugged into a PCMCIA device. I even installed Windows 7 onto the HDD using the USB in the PCMCIA.
I also tried a mini PCIE to USB adapter in the WWAN slot. That worked as well, but I did not try to boot...
