hi so i download the hid bootloader from ojetive development and got myself the usbasp and then flash the code and fuses, but then when i plug it into my computer it isn´t recognise by the computer so i read the readme.txt file and found this:
The firmware is flashed into the upper 2 kB of the flash memory and takes
control immediately after reset. If a certain hardware condition is met
(this condition can be configured, e.g. a jumper), the boot loader waits for
data on the USB interface and loads it into the remaining part of the flash
memory. If the condition is not met, control is passed to the loaded firmware.
and ask myself which pin i have to use to enter into bootloading mode
so that´s my question, any ideas?

I've never used that bootloader, but I would imagine it's set in usbconfig.h, like the rest of the settings for V-USB. There are a lot of options in that file, s'probably somewhere.
