Hi Folks,

I have build the AVR-Doper and it's working very well on my XP machine, but on my Vista laptop the driver won't install.
It's saying something like

the system can not find the file specified

I tried various suggestions done in this post; http://forums.obdev.at/viewtopic.php?t=406
The only thing that helps a little bit is what Toshas suggested

"just change "usbser.sys" -> "brusbser.sys"

If i change this in the Avrdoper.inf file, the driver installs and in Vista there is an extra comport(Com6).
But when i start then Avr studio it won't find the AVR-Doper.
I need the Doper in CDC mode because i'm using Bascom-avr and Bascom don't support HID mode.

Somebody a idea to get it working?

Thanks,

CDC mode does not work reliably on all operating system / hardware combinations. Osamu Tamura maintains a list of compatible and incompatible systems in his AVR-CDC project.

hi guys ,the cdc driver for window Vista is ready now , osamu tamura san had fix the problem with the low bulk transfer. go to his home page and u will find the driver

Yes, Osamu has done a great job with that. But even with Windows XP or 2000, there are some hosts where the driver does not work. We don't (yet) know why.

hi there
I'v tried the CDC mode in many pc's and it worked 100% on xp and Vista
but the problem is in HID mode,on my old pc (amd sempron64 with k8t mb and VIA chipset)
it worked 100% on both modes without any problems , but on my new pc (amd athlon64x2 with k9n4 mb and nvidia chipset),it didn't work perfectly on HID modes (when i try to read or do something in avrdude it get freeze for 2 or 3 seconed then responed but sometimes it doesn't response at all , but in CDC mode it's working 100% in avr studio (but the same problem as HID mode in avrdude)
so in my opinion the CDC this time is realiable than HID mode.
anyway i would like to tell u that I'v finished the AVRmini Doper programmer , so may i upload it and share it on this site?
