Ttelmah, thank you very much!
There's a strange behavior, 32 MHz reach only when OSC_16MHZ set in oscillator setup. Datasheet says 8 should be. Not a matter.
Once more, thanks!

If you need only data, the better variant is ex_usb_hid.
Your device wold be defined as standard and no drivers needed. But you'll need a bit more special software for your PC.
With ex_usb_serial yo ...

Hello!

I Have a pic16f1827(
#include <16F1827.h>
#device adc=8

The device doesn't work with ZOTAC ION ITX A Series (E) motherboard under Win7 at all. Not recognized by OS.
But works succesfully works with most computers.

I'm using 4.093 and not able to compile with 4.099.

What if I ask you to compile my project? Rolling Eyes

just to try

Oh, that's so logic that CPUDIV2 means that cpu frequency'll be divided by 3. Very Happy

Now I know why I should use such clock parameter.

But the problem of bad recognition still exists. Embarassed

Hi!
I had a pause in creating the device, and now I continue... I still have problems with usb recognition on some computers.

That was surprise for me with the clock I need to write:
20 MHz - HSP ...

compiler 4.093
18f2550, Three computers with OS: win7, xp, xp
('bad' means there are more than 1 error device recognition per 5 connections)

... for 18f2550

There can be only one point where I can interfere with usb - I've added timer0 interrupt.
I toggles led on and off.

By the way, don't tell me that there can be no errors in ccs! Timer0 DIV_128 and ...

Thanks, but I have already read about this in datasheet. I always read it before I want to create something.

Datasheet says that my device can be low-speed and a speed. As I don't need hi-speed tra ...

Error code 10

It seems that the device is not recognised when microcontroller clock frequency is other than 48 MHz

I use 20 MHz crystal -> HSPLL -> PLLDIV5 -> CPUDIV#

Sorry for poor english
In XP:
"USB device was not recognized"... An yellow ballon near to tray.
In device manager I see exclamation sign near hid device icon.

Hi! I've found a strange feature of your usb library:
When I connect my device to computer with Win7 it's always defined by OS.
When I connect it to computer with winXP, it can be defined, and can b ...

Emm.. Thanks!

And will there be any effect if i just change
