2009-05-26 16:56:07 USB-to-serial on BF537

Message: 74620
I am trying to get some USB-to-serial adapters working with a custom BF537 design (similar to the Stamp) running uClinux-dist-2008R1.5-RC3. The isp1362-based USB interface works fine with USB flash drives, so I think the hardware is OK. I have two USB-to-serial adapters:
AirLink101 AC-USBS, which I believe uses a Prolific PL-2303 chip.
SIIG US2308, which probably uses a FTDI chip (implied several places, but I haven't verified).
I have been trying to follow the HOST (not gadget) instructions from docs.blackfin.uclinux.org/doku.php?id=serial_over_usb&s[]=usb&s[]=serial&s[]=converter Both the ACM and generic USB serial driver instructions start off with the commands:
mount -t usbfs none /proc/bus/usb/
cat /proc/bus//devices
I can't get either of those commands to work:
root:~> mount -t usbfs none /proc/bus/usb/
mount: mounting none on /proc/bus/usb/ failed
root:~> cat /proc/bus/usb/devices
cat: /proc/bus/usb/devices: No such file or directory
root:~> ls /proc/bus
root:~>
My USB configuration follows:
Device Drivers
USB Support
<*> Support for Host-side USB
<*> ISP1362 HCD support
(65) GPIO for Interrupt
<*> USB Modem (CDC ACM) support
<*> USB Mass Storage support
--- USB port drivers
USB Serial Converter support --->
<M> USB Serial Converter support
[*] USB Generic Serial Driver
<M> USB FTDI Single Port Serial Driver (EXPERIMENTAL)
<M> USB Prolific 2303 Single Port Serial Driver
I have been building in my other drivers, but the help for the USB Generic Serial Driver suggested that the USB Serial Converter support should be complied as a module. I don't know if having a mix is a problem or not.
If I don't have anything connected to the USB port on startup, the console output looks like this:

if you dont enable the USB filesystem, then mounting it will of course fail. you have to enable it in your kernel configuration first.

Seems obvious now Thanks.
I got the SIIG adapter working. The AirLink adapter using the Prolific chip isn't working; it causes the message " usb 1-2: can't set config #1, error -32” to be printed when it is plugged in. That is OK; I don't need both anyway.
