I have an embedded device, on which I use the USB gadget USB interface to either make it available as a mass storage device, or enable access over USB serial using the
While I can connect to the device using
modprobe usbserial on Linux, how can I do it on Mac? It only gives me the following:
$ ls /dev/tty.* /dev/tty.Bluetooth-Modem /dev/tty.Bluetooth-PDA-Sync
This is coming from the
dmesg, not sure if it is related to the device:
USBF: 10410.547 AppleUSBEHCI[0xffffff801379c000]::Found a transaction which hasn't moved in 5 seconds on bus 0xfd, timing out!

Linux (native) might have the right drivers, but not OS X.
It will help to know the output of
lsusb and what happens if you try to follow this article, for both native Linux and OS X.
The differences between the two might be instructive.
