How to connect a USB device on the ch340 or ch341 chip to Arduino using USB Host on chip MAX3421ee?

there's a USB device on a chip ch340 or ch341 USB output-DAD
need via USB-MOM, for example MAX3421ee connects to the Arduino and a ttl.

Can't find bundles ch340(ch341) and MAX3421ee .
May advise is MAX3421ee to use something else , I watched the documentation on ch376 failed.

I personally have no problems with it.
I used ElecFreaks USB Host Shield on the chip MAX3421PE.
Loaded up the sketch, looked how it all works. Everything is working fine.
Only practical application of the not - Arduino makes no sense to connect a USB device. Is that any USB joystick suddenly want to turn into a MIDI controller, for example.
you probably tried to shield , but have not tried it in conjunction with the controller ch340, because it needs such a driver in the library, with FTDI, CP210X, PL2303 is not suitable((((
The link above is not there in the library support ch340/1
And the practical application of such a device - a solar inverter that has a regular monitoring system, but there is a Protocol of the survey parameters, and out of the USB-dad on the CH341 chip , you need to interview arduinos and send to the server statistics data. - coby.Tillm commented on March 20th 20 at 11:34
@judd21, what's the driver? There is a USB Protocol, connect the device, run enumeratio endpoints, and write/read them. - uriel_Kerluke85 commented on March 20th 20 at 11:37
