I just purchased the USB IR Toy v2.
Based on this forums responses, I tried several methods of upgrading my firmware but always ended up with the following:
fw_update -e -w -v -m flash -vid 0x04D8 -pid 0xFD0B -ix USBIRToy.v22.hex
U2IO flash erasing: FAILED.
Device is not found.
Operation aborted.
Then I removed the jumper and initiated the bootloader (since it installed on COM3) and now I am stuck with an LED light even if the PDG/PGC jumper is not on.
I don't have access to a linux machine or a Windows XP.
Any help is appreciated.
I tried windows 8.1 and Windows 10 Preview, both 64 bit editions, and it does not work to recognize the device to flash it. The safest way is doing it from a 32 bit Windows XP operating system. 32 bit Windows 8.x might work but I did not try that (has anyone tried that?).
I played a bit with Oracle VirtualBox but was not able to forward a non-recognized HID to the guest OS (windows xp), so I looked for something else.
I don't have any machines running Windows XP at home but what I did was creating a bootable USB stick from a 'Windows XP based Live CD' using Rufus (http://rufus.akeo.ie/ (http://rufus.akeo.ie/)). You will need to find an disc image with Live CD obviously. I also have copied the folder with the tools and firmware on the same on the same USB stick.
Then it worked okay to flash it:

the console is in Russian but you get the "picture." When it's loaded, it is slow to recognize the devices in device manager and there many that would be "not recognized" but it should do ok with COM ports and HIDs. For me it worked just to plug the USB IR Toy 2 to USB and use 1 as COM parameter.
Hope this will help.
