Who has run the sample program HIDDevice_Custom?

I can't overcome the line The program hangs-up on this line.

The device is been detected and determined properly by Windows' Devices and Printers and by USBlizer...

Have you posted to the correct forum? Sorry I see you have, somehow I've ended up getting posts to the basic forum which I never use, I never had that happen before.

My problems concern "New USB Device Library Released!" topic, because I apply to this theme. What another one do you propose?

Is there any example about VCP for STMF407VG the one in the libstock dosn't work

Hello Members;

I am not sure what I am doing wrong. I am trying to use "USB device library" with 18f4550 but could not pass enumeration? Tried both hardware and using isis gave same result.
I successfully used legacy HID class without issues both hardware and with Proteus.
This is with MiroC Pro and Vista 64bit.
Note: I just used the Hex provided with the library, file "HIDDevice_Custom.hex" with the circuit below.
2 screen captures: 1 with legacy HID library, everything passes, 2nd with USB device library, fails enumeration.
Thanks for the help,

Hi everibody!

Tx DATA SIZE

I'm a newbie about MikroC CDC.
I try to send more than 64 bytes of packet size.
But the USB transmit hangs up.
I try to modify the wMaxPacketSize in descriptor file, without success.
Which is the right way to use bigger packets i.e. 128 bytes?

Thanks:
Peter

Hello,

Unfortunately, the USB device library was written to be used with the maximum packet size of 64 bytes, as defined in the USB specification.
Library is not tested with a packet whose size is larger than 64 bytes.
It's possible the larger packets can be send without any loss, but it simply can't be guaranteed within the specification, and that is the reason we haven't tested it in special cases beyond the specification.

Best regards,

Looks Supercool

Hi ME, does this library support PIC32MZ? If not, any idea when? Thanks

Hi,

Unfortunately, at this moment USB Device library doesn't support PIC32MZ,
but I have passed to our development team to add support.

When I have more information when will be added support, I will post it here.

Best regards,

Hello
I tryed to use this library with the PIC24FJ128GB202 (204).

CDC class works good but have only one problem - each 3-4 minutes i hear from Windows sound like USB device disconected and terminal programm needs to restart. Device in list of devices always.

What can to do with this ? Have any differents bettween PIC24FJ128FB202 USB modules and other PIC ?

Sorry, was enabled a WDT

So, with the PIC24FJ128GB202 (204) works perfect.

PIC init Only one desire - buffer size up to 256
In current version the maximum packet length only 63 bytes (not 64).

Thank you.

Hi renew,

Welcome to the MikroE forum.

Please check if you have turned off watchdog timer in Project Settings.

Hi. I`m use USB lib for pic18f2550 mcu. It works well, but on some PC in particular with USB 3.0 the device is not detected and responds "USB device not recognize". I'm not sure I understand why that would be a problem.
