Hi
I've pruchased a Devantech USB-ISS multi-protocol USB-module, and I
would like to add it to the avrdude. Plugging the module into the
USB-port automatically creates a serial port, through which the device
can be accessed.
I plan to use the virtual serial port to communicate with the
Arg, never mind...
USB-ISS cannot be used as a programmer after all. With current firmware
the SPI mode does not allow the reset to stay down between SPI-transactions.

You need read/write permission.
As these devices are created dynamically, you cannot do that with a
plain chmod, but you have to consult your systems dynamic device
facilitie's documentation.

However, avrdude is reading stuff in /proc
According to your original post it's clearly accessing /dev:
open(/dev/bus/usb/007/001, O_RDWR) = -1 EACCES (Permission denied)

Sure, device permission problems.
This returns -1 and i can't figure out why.
That's the way permission problems manifest under Linux: you can still
open the USB device in libusb (apparently, this is done through

I got it working now. Directory permissions must have been wrong.
I did: sudo chmod -R +X /dev/bus
Hi,
I just got a usb AVRISP. What permission should i fix? :
strace avrdude -p m8535 -c avrispmkII -P usb -v -U flash:w:proj.hex
open(/dev/bus/usb/007/001, O_RDWR)= -1 EACCES (Permission denied)
...
dev/bus/usb/007/001 exists, but i don't know what to do about the
permissions in this

I have a question,
I tried looking but couldn't find an answer, Does avrdude support USB
under windows? I know it didn't as of last march.
If not anyone know whta it would take to add support?
