Hobby Components Arduino Compatible Uno+ (HCARDU0100)

Hi Andrew,

I didn't download any drivers prior to it stopping to function.
I did download drivers from the HC forum link. There were two , an HCMODU0076 Windows driver and a CH340 Driver Master
Neither would install at first.

The Device Manager showed the COM number and it appeared healthy but it had the word "RAMPS" in front of it.

I went back just now and tried to install the same HC driver again from my download file and it installed.

I uploaded the Blink sketch and it works.

The Device Manager now shows "USB-SERIAL CH340 (COM12)"

All appears to be back to normal once again. So, I'm guessing the driver got blown away some how.

You're a genius!

That's great. TBH for a while now Windows update will automatically install the correct CH340 driver so there's normally no need to download the one from the link from above. It's just sometimes someone will download the driver from some other source and I know that there are version(s) of the CH340 driver out their in the wild that don't work properly. Anyway glad you managed to solve it.

Hi Andrew,
Hooked up a new UNO+ and started with the same COM error. Went back and found the driver file for the CH340. It would not install. Tripped on a CH341 driver Master in the CH340-Drivers-master.zip It installed A-OK
Something very unusual going on but seems to be up and running. Trying to figure out the HCMODU00124 RTC Module
Will respond in that thread with questions about Libraries for the DS3231 and proper use of the RTC.

The only thing I can think of is that you still have a bad driver installed. The problem is even if you install a good driver over the top of a bad one Windows will still keep a copy of the old one and may reuse it again after the Uno is unplugged or the computer is rebooted. If the problem happens again you could try stripping out all installed copies of the driver. To do this follow these steps:

1) Open up device manager. You can find it by typing typing 'device manager' in the start menu search box.

2) In the device manager window that opens up find the COM port for the Uno+. It's under 'Ports (COM & LPT)' as USB Serial Device (COMxx). If there's more than one COM port listed you can confirm you have the right one simply by unplugging and reinserting the UNO to see which one disappears and reappears.

3) Once you have located the correct one right click on it and then select 'Uninstall device'. This bit is important - In the window that opens up click the 'Delete the driver software for this device' checkbox and then click ok. This will delete the driver rather than just uninstalling it.

4) Once the driver has been uninstalled and deleted unplug the Uno+ and then plug it back in again. When all copies of the driver have been deleted you should should see the Uno+ listed as an unknown device. If it automatically installs a driver again then repeat step 3 until you have removed all copies of the driver.

5) When you have done this then reinstall the driver from this forum thread as you've done before.


As I said though, I wouldn't bother doing this unless you get the problem again.

Thanks again for your ongoing support.

This is why I come back and buy from HC.
