Firmware location issues with ti_usb_3410_5052
 
All,
I'm currently setting up a device which uses the ti_usb_3410_5052 driver. It is properly detected, and gets as far as loading the firmware. However, it is unable to find the firmware. It is looking for either ti_usb-v0451-pf432.fw (which does not exist anywhere on my system and a google search shows may not exist at all) or the generic 3410 firmware - ti_3410.fw, which is in /lib/firmware. Below is relevant dmesg output.

Using rmmod, then modprobe:

USB Serial support registered for TI USB 3410 1 port adapter
USB Serial support registered for TI USB 5052 2 port adapter
ti_usb_3410_5052 2-1:1.0: TI USB 3410 1 port adapter converter detected
usb 2-1: firmware: requesting ti_usb-v0451-pf432.fw
usb 2-1: firmware: requesting ti_3410.fw
usb 2-1: ti_download_firmware - firmware not found

usbcore: registered new interface driver ti_usb_3410_5052
ti_usb_3410_5052: v0.9:TI USB 3410/5052 Serial Driver

Simply unplugging and replugging:

One final note: This device is known-compatabe with the 3410 driver (it got one in plain view...). However, because its a slightly different device that never had its product id inserted into the 3410 driver the version I'm using is slightly modified - I had to change one of the product ids in the driver. This seems to have no negative effect, as the driver still loads and runs. Hopefully this is irrelevant to issue at hand. However, I've included this just in case.

Any help or advice you can offer is much appreciated.

Thank you,
mageman
