Arduino and CH376 usb host module, reading USBMIDI

[im_ilua]

Hi.
I'm trying to receive MIDI USB massages via CH376 USB host.

It's the only module with USB HOST capabilities in my area and I had no time to wait for any deliveries. I found datasheets, where I found some words about the possibility of peripheral device connection to USB host, so I went off with that module, however I've seen a lot of posts about CH376, where its used only for reading/writing data to USB flash devices.

Im using Arduini Pro Micro and the basic 4-wires UART connection. My midi only has a USB output. The code is here. Its based on a random sketch I found online. I didnt want to use CH376msc library, cause at first it seemed too complicated and still It didnt have a basic usb device massages receiving capabilities. Ive been trying whole week to make things work but the only thing I can do with that module now is a Baud rate change and connection tests. I cant receive any massage.

my code is here
SERIAL.ino (10,7 КБ)

Datasheets: 1. https://www.wch-ic.com/downloads/CH376DS1_PDF.html
2.CH376DS2.PDF - NanjingQinhengMicroelectronics

I have two questions:

1. Is it even possible to make it work with this CH376 USB host module without getting too deep (into firmware, voodoo, homeopathy and stuff) ?
2. What am I doing wrong?

Thanks in advance.

I'm facing the same problem as you. I tried using a logic level converter to ensure the voltage was synchronized between the CH376 module and the Uno, but it still doesn't work

I think it's only for using a USB thumbdrive.
That's the only implementation I've seen of it.
(If, technically, on that basis, it's a 'Host', then it's limited not general.)
