Problem with enumeration and EasyHID

[jizyjuice]

Well I changed the config files and took out the pause in the code. Still no enumeration. Could this be a hardware problem?

I attached everything the same way as the 4550 pictured by easyhid, but just adapted to the 2550.

There's always a chance for a hardware problem. But that's a liitle hard to troubleshoot on this end.
The schematic is good though.

Just noticed you have a DEFINE LOADER_USED 1

Are you using a bootloader?

[jizyjuice]

No im not, im using melabs pic programmer. Should I take out that define statement?

Okay, Finally I got the thing to show up on the pc! A 1k pull up resistor needs to be put on D+ and Vsub!! I was under the assumption that there was an internal pull up resistor there. Maybe I didn't configure that in the code.

Well Thanks for everyones help so far.

The windows doesnt recognize the device tho. So it wont enumerate as an HID device yet.

[Darrel Taylor]

There are internal pull-ups. And EasyHID configures them for Full-Speed, so you shouldn't need external ones.

Did you use all the configs from post #11?

In particular _VREGEN_ON_2L.

Your original configs had that turned OFF, just want to make sure it's turned ON now.

Should I take out that define statement?

It doesn't really matter, it's fine even if not using a bootloader. But if you were using a bootloader it may have caused problems with the config settings, so I thought I'd ask.

I used the config code from post 11, but _BORV_2_2L and _FCMEN_OFF_1H dont seem to be define for the 2550, so I took them out.

Is there another file i need to include to get these fuses to work correctly?

[Darrel Taylor]

You still have MPASM 5.02 so it's _FCMEM_OFF_1H
That'll change after you upgrade MPASM.

_BORV_2_2L is defined for the 2550. I can see it in the .LST file in your .ZIP in post #10
Can't image why there would be a problem with it. But since it's in the same line as _VREGEN_ON_2L, it makes me wonder if there's something else wrong with that line which caused the error.
