| USB problems on PIC16LF1455 |
 Posted: Wed Aug 03, 2016 8:20 pm |

Hi everyone.
I have a project using HID USB connection from circuit to PC.
In my project, I used PIC16LF1455 and used USB driver of CCSC (ver 5.058).
The first, circuit run normally, but after that about 1-2 hours, the circuit hangup (the PC not recognized USB), must power off and on again, the circuit must run.
I also add WDT, BROWNOUT to reset but result not change.
Pls help me to solve this problem.
Thanks all.

Look at the power settings in your PC.
It is probably going to a low power state, and trying to put the USB to such a state. The standard code does not support this.
<http://helpdeskgeek.com/windows-xp-tips/prevent-windows-from-powering-off-usb-device/>
The same applies to W7. |

Thanks for your helping 
I tried but it not change, the PC is turned off sleep mode or hirbernate. :((
Maybe problems with WDT or anythings else in my program?

I have to 2nd Mr' T's suggestion. Just because the PC is not in 'sleep' or 'hibernate' doesn't mean that the PC USB drivers are not automatically going to 'sleep'. You need to find and alter the PC USB 'options'. It can also be in the BIOS setup ! new PCs (after 1999) have a LOT of setup/config options in the BIOS and Windows has several 'layers' ANY of which WILL cause the USB ports to 'sleep'.
If possible try another PC to see what happens.

First, have you disabled the selective suspend feature. This really is the most likely cause of the problem:
<http://www.sevenforums.com/tutorials/147369-usb-selective-suspend-turn-off.html>
It causes grief for a huge number of devices. It really must be off.
It is on by default in Windows, which is why there are so many threads telling you how to turn it off....
Then, do you have the connection sense wire on the USB?.
(This is _required_ by the USB specs, unless your device is powered directly from USB...), then your USB initialisation code should change to:
| Code: |
//at the top of main
int1 usb_old_connected = FALSE;
//your other initialisation
usb_init_cs();
//Then in your loop
for(;;)
{
if (usb_attached())
{
if (usb_old_connected==FALSE)
{
usb_token_reset();
}
usb_task();
if (usb_enumerated())
{
usb_old_connnected=TRUE;
//your usb and other code
}
else
usb_old_connected=FALSE;
}
}
|
This forces the USB stack to re-initialise if the cable is disconnected/re-connected, or enumeration is lost.
'But', I hear you say - I'm not disconnecting the cable....
The Windows USB driver will electrically disconnect and re-connect in certain circumstances. These are caused by certain types of stack overflow at the Windows end, and also on multi-processor machines in particular. If your device can't handle it, it will become hung..... |
