CHIP MAXIM3421 #765

Open TeatrSveta opened 1 year ago

TeatrSveta commented 1 year ago

Please tell me if there are any differences in the work of the library for USB HOST SHILD with the MAXIM3421EE chip? This type of boards began to appear on the market since the middle of last year. Unfortunately, your library does not work with such boards.

Lauszus commented 1 year ago

Please send me the exact part number? There is no such chip as MAXIM3421EE?

TeatrSveta commented 1 year ago

Hello, Lauszus. Thanks for the answer. In attachment - foto of the board with the MAXIM chip MAXIMUSB Exact inscription on the chip "MAXIM3421EE TJ939+NTCZ" There is a mention of a similar problem here https://forum.arduino.cc/t/arduino-usb-host-shield-not-registering-usb-device/1028206 Regards, Alexey.

Lauszus commented 1 year ago

Please take a picture close up of the chip itself.

Lauszus commented 1 year ago

This is just a regular MAX3421E chip. I suggest you contact the reseller for help, as it should work.

TeatrSveta commented 1 year ago

Thank you I'll do

Checking USB device communication.

Waiting for device...

Please advise - how to carry out further diagnostics of the board and USB connection? Perhaps you have encountered similar cases? Regards, Alexey.

touchgadget commented 1 year ago

Looks fine to me. SPI long test passed. The GPIO failure is normal. Plug in a keyboard or mouse and the program will dump out the device descriptors.

TeatrSveta commented 1 year ago

Thank you for your reply. I did the steps you listed. With different keyboards and mouses. Unfortunately the answer from the board is the same -

Checking USB device communication.

Waiting for device...

The feeling that some little things are missing - contact, settings and that sort of thing. Which?

touchgadget commented 1 year ago

One possibility is 5V is not reaching the USB connector. Do mouse or keyboard lights come? Use a multi-meter to check for 5V. Double check the soldering for 5V. I do not know what else would prevent this from working.

TeatrSveta commented 1 year ago

Solved! The jumper for VBUS turned out to be key. All descriptions of this type of boards indicate that you need to install a "5V" jumper. In this case, USB does not work. As soon as I broke the "5V" jumper. And put the jumper on "3.3V" everything worked. Passed the board_gс test to the end. USB-MIDI dump utility sketch successfully launched. I was able to test this change on 9 boards that I have. Everything worked. The only thing - do not ask me why it worked that way. ;-) Thanks for your support and help. Alexey

touchgadget commented 1 year ago

Wow, sounds like the 5V and 3.3V pads are labelled incorrectly. USB devices need 5V, not 3.3V. Score one more defect for cheap clone boards.

xxxajk commented 1 year ago

Even more fun when they put on the wrong chip :-D

May i see the board after breaking the 5v jumper sir?. Thanks

TeatrSveta commented 1 year ago

Hello. Here is one of them.. If necessary, I can provide a video of the operation of such a board with a mouse or midi keyboard. ;-) IMG20230215111733

Very interested sir, I will subscribe your YouTube channel sir. Thanks

I do the same to put the jumper on "3.3v" and it's work for mouse or keyboard but not for usb device like guitar multi effects sir. Is this because the vbus output is not 5v sir?. sorry my english.

TeatrSveta commented 1 year ago

I think that a Usb device such as a guitar will most likely work if you try to use the USB-MIDI dump utility sketch from the applications to the USB_Host_Shield library_2.0 or similar.

I did sir, but no lucky.

IMG20230215164805

VBUS is 3.84v not 5v. Thanks

touchgadget commented 1 year ago

There is another recent message thread about 3.9V out the USB host connector. This sounds to me like there is a short circuit between the 3.3V and 5V power rails. I have no idea how to fix this.

xxxajk commented 1 year ago

That's what you get for a crappy clone. Don't buy knockoffs.

touchgadget commented 1 year ago

Are there authentic Circuits@Home USB host shields for sale any more? I guess the SparkFun board is authentic but it is not 100% compatible with the Circuits@Home shield. The SparkFun forum has some note on how to make it work with this library but only for Uno.

xxxajk commented 1 year ago

Looks like I may have to produce them, as it looks like @Lauszus got out of the biz. If I do that, expect a MUCH BETTER design than the classic.
