Hi,
We are trying to setup the USB test suite using a Keyspan USB-Serial adapter
(USA-19HS). We followed the "USB Testing on Linux"
(http://www.linux-usb.org/usbtest/) instructions. This particular adapter
was not listed on the usb test page but other USA-19 adapters are. It uses
the same driver as other keyspan models and seems to use the same mechanism
to upload the firmware in the driver. But when we attempt to load the
hexfile using fxload, we get "can't modify CPUCS: Broken pipe" on the first
USB control message fxload is trying to send.
Here are some steps we did:
[EMAIL PROTECTED] hotplug]# fxload -V
May 3 2004 (development)
[EMAIL PROTECTED] hotplug]# cat /proc/modules
keyspan 117404 0 - Live 0x22a63000
usbserial 22264 1 keyspan, Live 0x229ed000
...
# unplug device / replug device
[EMAIL PROTECTED] hotplug]# rmmod keyspan
[EMAIL PROTECTED] hotplug]# lsusb
Bus 001 Device 037: ID 06cd:0121 Keyspan
Bus 001 Device 001: ID 0000:0000
[EMAIL PROTECTED] hotplug]# fxload -v -t fx -D /proc/bus/usb/001/037 -I
usb/testfw
microcontroller type: fx
single stage: load on-chip memory
open RAM hexfile image usb/testfw
stop CPU
can't modify CPUCS: Broken pipe
[EMAIL PROTECTED] hotplug]#
We've tried fx, fx2, and an21 type of microcontrollers all with the same
result. We've disabled the automatic loading of the keyspan driver in
modules.usbmap as suggested on the usbtest page. We have also tried to
insert the usbtest script into usb.agent to load the firmware through
hotplug immediately after plugging in this device with the same result
("Broken pipe").
We could not find step-by-step instructions for this test procedure, so we
are not entirly sure we are going about this the right way. Any help and/or
pointers would be appreciated.
Thanks in advance,
-- Philipp
BTW: We are trying this on an i686 with kernel 2.6.5 (Fedora)
