[libhid-discuss] USB libhid is writing to PIC but errors out reading from it.

[Daniel Yount]

Well I had tried out the bootloader and I get the same problem. It writes to it as it says Querying Chip.
but then it gets disconnected when trying to write from the chip. No difference in the problem of either program.

I was told that D+ was the write to chip line and D- was the Read from chip line. 
checked out the connections they seemed to be good, but will debug the lines later
have to go somewhere. Wondering what could be the deal on this chip and bootloader if it has a not
read option or should it be readable from the get go?

I was in the wrong on this one, I was using the Bootloader firmware form the Generic HID Bootloader.
I installed the accompanying HID Bootloader for the HIDBootloader and it all worked. or at least found
it will now test the uploading.

Thanks for your help.

I tried to get the Microchip HIDAPI Bootloader to find my 18f2455 chip 

and it would not. Just says disconnected at the bottom and give me no
options other than to kill the window.  The chip is in boot loader mode
i.e RB4 to ground and 10k to 5v usb + bus. It also shows up in the dmesg & lsusb list.
