USB Host Shield Fix

- Here is the issue and fix for those having USB Host Shield problems with Arduino (and Padawan 360 for example). The "AHC" chips can be purchased from Aliexpress no problem and are very cheap. You don't need to be a wizard at soldering, but solder paste certainly seems to help.

measure the volatage on the 3,3V Line with the HC125 - the 3,3V line goes up to 3,9-4,0V.... this voltage stop the MAX USB Chip... With a long USB Kabel on the Ardoino Schield - Drop the 5V voltage so much that the high voltage on the HC125 drop to 3,6-3,7V and the MAX still work.... In my test USB Shields work without a Voltage Pin on the HC125, lift the PIN 14 from the HC125 - pls reports y results
What are the symptoms, if I don't change it? The checker-skript from the library runs well till it stucks at "Waiting for device". (My device receives enough power. It lights up. And I tested other usb devices.) Always: Waiting for device :(
I received my host shield two days ago. Mine too has two HC chips and no AHC.
(Also: Instead of a MAXIM 3421EE TJ209 +ITED, I have a "MAX 3421EE 2228". Is this an issue?)
Hi, what happens if you don't change this chip? I have just received a host shield with a SN74HC125 chip, so presumably it needs changing?
by all means give it a try, but chances are yes, it will need changing.
I am having trouble getting the shield to operate the Xbox controller for the Padawan 360. I am using the Mega. The Xbox controller gets power and pairs but won't respond to any command. Is it the chip you mentioned in the video since I have the incorrect chip? Would this issue cause the Xbox controller not to work? I also have an after-market Xbox controller and I have updated the files and uploaded them to the Arduino Mega.
Most likely. Have a look on your host shield at the chip on the right hand side. It should be an "AHC" chip but many are fitted with a HC chip. This video explains in more detail: czcams.com/video/UVjqSA3u26k/video.html
Thanks for the quick reply. I watched the video, so I thought it might be the shield. Because of that, I ordered an Arduino mega ADK with the USB. I'm not sure I want to handle those tiny solder points. Your tutorials have been of great help. If I get the problem solved, I'll send a message so others can learn. Thanks again. Bryan
@@bryancombs4636 it’s not actually that scary so long as you have the right tools and solder paste is a huge help. ADK board does away with any of this, just make sure you select the ADK mega when uploading the sketch (I have a video on that too!)
Thanks for the info. I received the Mega ADK and tried to upload the sketch, but it is still not working. I get the receiver to blink slowly, then bind with the controller. The controller has a light on the top left that goes steady. It just remains lit with nothing else working. Did the same with the Shield. The Mega appears to be uploading since the software says upload complete. I have tried changing the PID for the Xbox receiver, as described in one of your other videos. No luck. Started over fresh with no luck. Same result. Only the top left light on the center button on the Xbox lights up after binding, and nothing is working. I ordered another Xbox controller, thinking maybe it's a controller issue. The PC reads the controller, and the buttons appear to work on the PC. At a bit of a loss.
Question: If I cannot get this thing up and running, can you upload the sketch if mailed to you? Please let me know if that is something you do for customers.
Thanks,
Bryan
I could not get the ADK to work with the transmitter and receiver I had. I ordered an OEM TX and RX. They came in, and it worked right off the bat with the MEGA. It also worked with the shield with the bad chip number. Don't know why. I couldn't get the ADK to work, so I will leave that for now since the Mega seems to be working. Makes lots of R2 sounds. I don't have drive motors yet, but they are on order. I am hoping those work with the system as well when they arrive. But since the sound works with the controller, I am hopeful. It looks like my main problem was aftermarket TX and RX.
