2. Troubleshooting
Q1: What interface do the ACR38 readers support?
The ACR38, ACR38T and ACR38DT are available on USB interface only.
Q2: I get no response from my USB Reader.
The USB drivers provided by ACS will work for the following Operating Systems: Windows 98,
Windows ME, Windows 2000 and XP. The USB reader will not run under: DOS, Windows 95,
and Windows NT.
Please check if your USB port is functioning properly. It is possible that there is a physical
damage with your USB port. Plugging in any USB device to the port will make Windows react.
Make sure you installed the correct USB driver. Check on Windows Device Manager if “ACR38
USB Smart Card Reader (Proprietary Mode)” or “ACR38 USB Smart Card Reader” is listed.
Q3: ACR38’s green LED keeps blinking, while ACR30’s doesn’t. Is this normal?
Yes.
Q4: An error message says the reader insertion monitor error retry threshold reached.
Cause: The ACR38 USB smart card reader was disconnected in the middle of a session on
Windows 98/ME. The Microsoft Smart Card System dialog prompts the following message:
Reader insertion monitor error retry threshold reached. The parameter is incorrect.
If you click OK to close the message box, another dialog might pop-up saying:
Reader monitor ‘ACS ACR38U 0’ received uncaught error code. The parameter is incorrect.
If one or both of these messages appear, the ACR38 smart card reader will not work on the
current Windows session, even if you reconnect the device.
Solution: You need to reconnect the ACR38 smart card reader and reboot the system. On
Windows 98 and ME, the Smart Card Resource Manager detects the ACR38 USB smart card
reader only upon bootup.
Q5: Does ACR38 ACS Synchronous API driver (Proprietary Driver) support auto-download
capability?
No
Q6: Does ACR38 PC/SC Driver support auto-download capability?
Yes
Q7: Does ACR38 ACS Synchronous API driver (Proprietary Driver) support Microsoft
Windows Update capability?
No
Q8: Does ACR38 PC/SC Driver support Microsoft Windows Update capability?
Yes
Q9: Which is a better platform? PC/SC or Proprietary?
Depends on your requirements.
Proprietary drivers and its API's are easier to use. If your applications require PC/SC-compliance, (or if
you want your application to run on different reader brands) then you should use PC/SC. For beginners,
Proprietary is a better choice.
