Accessing USB Programmer With avrdude

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I'm having trouble trying to access a USB device under Fedora 7. I think
udev might be my problem.

When I try using avrdude with this line:

[rlc@bobcp4 atmega644]$ avrdude -c usbtiny -p m644 -P usb -U
flash:w:blink_pb3.hex

I get this error message:

avrdude: Error: Could not find USBtiny device (0x1781/0xc9f)

This is what lsusb says:

[root@bobcp4 ~]# lsusb
Bus 001 Device 001: ID 0000:0000 
Bus 003 Device 001: ID 0000:0000 
Bus 004 Device 006: ID 0e6a:6001 Megawin Technology Co., Ltd
Bus 004 Device 005: ID 0424:2228 Standard Microsystems Corp.
Bus 004 Device 004: ID 0424:2602 Standard Microsystems Corp.
Bus 004 Device 002: ID 0424:2502 Standard Microsystems Corp.
Bus 004 Device 001: ID 0000:0000 
Bus 002 Device 002: ID 1781:0c9f 
Bus 002 Device 001: ID 0000:0000 

And the device is described here:

http://ladyada.net/make/usbtinyisp/

(I bought the kit and built it.)

I added a rule named '98-usbtiny-rules' to /etc/udev/rules.d which
contains this line

*SUBSYSTEM=="usb", SYSFS{idVendor}=="1781", SYSFS{idProduct}=="0c9f",
GROUP="users", MODE="0660"

But avrdude still can't seem to find the programmer. Am I right in
believing that I need a udev rule, and if so, does the above rule look
correct for what I want to do? Or am I missing another issue?
