USB-Tap problem "Library not found"

MS_IMC — Thu, 29 Oct 2020 08:56:39 GMT

Hello,

i did post in this thread that we got some problems with some of our USB-Taps.

Code:

Hello,we got the same problem "Library not found" at some USB-Taps. We use the USB-Taps for production
and this behavior suddenly occur and seems to be permanent on the respective USB-Tap, so there
are useless for us.We tried the "broken" usb-taps on different PCs without success. We can run on the same
PCs w/o changing anything, a "healthy" USB-Tap with success.In sum we got 8 USB-Taps from which 4 of them seems to got broken. One of them we just got yesterday.This is pretty disappointing so any help is appreciated.Is there any known issue about the USB-Taps we should know — I.e. ESD problems –

Any help is appreciated.

Regards,
Marc

Hi,

There was an issue with previous version of USBTap.

See below for details.

==================================================================================================================================

CodeWarrior USBTAP Product Notification

An early revision of the CodeWarrior USBTAP has been sometime shown to be sensitive to Electrostatic Discharge (ESD) from human touch. Users should take care to ground themselves when handling the USBTAP unit.

This notification applies to following parts numbers and revisions:

CWH-UTP-STC-HX (900-20681)

CWH-UTP_PPPCD-HX (900-75094)

CWH-UTP-PPCC-HX (900-20659)

CWH-UTP-ONCE-HX (900-20681)

CWH-UTP-CF-HX (900-20682)

How to tell if your USBTAP is susceptible to ESD?

Look at bottom on UTAP case. The sticker on the bottom of the case will show 900-xxxxx. Check to see if this matches one of the numbers above.

How to tell if your USBTAP is affected:

If you suspect your USBTAP is no longer working due to ESD, try the following:

A. Setup was working fine and then stopped working.

Check to see if Windows can recognize your USBTAP:

- Plug your USBTAP into a USB Port of a computer running Windows XP

- Wait 30 seconds

- Does "Windows found new hardware dialog appear"? If yes, then your USBTAP has not been harmed by ESD

- Open windows "Device manager"

- Expand "System devices" category

- Does "CodeWarrior USBTAP" appear on the list? If yes, then your USBTAP has not been harmed by ESD

B. Having trouble during initial setup.

Update and reinstall the USBTAP driver

- Ensure you have the latest CodeWarrior release. Updated drivers may be included

- Drivers are found in the "CodeWarrior" program file directory under the ccs/drivers directory

- Reinstall with the directions are included in this directory

- Repeat step A.

If both A or B fail and the USBTAP is one of the 900-xxxxx series tap, you probably have experienced an ESD related failure and the unit needs to be replaced.

Returning you Unit:

If your unit has failed, please follow the RMA instructions at the following link:

Hi Pascal,

thank you for the information. We don't have one of the mentioned item-numbers.
Our USB-Taps item numbers are USB-Tap ONCE 900-75116, some of them are Rev. C others are Rev. X2.
I have also tried the mentioned driver update but it did not help.

It seems that when we communicate with a working USB-Tap to the target, the red LED (Run/Pause) is
always shining. With the "broken" USB-Taps the red LED never shines.

Regards,
Marc
