felis / usb_host_shield Goto Github PK

Hi,
i’m having trouble using USB Host Shield 2.0 on a barcode scanner. The barcode when reading the code, does not output in the Serial Monitor and after that is stay in a dead state (It cant trigger), coming back to read new codes after a few seconds (after two another configurations). I’m using USBHIDBootKbd and the arduino Uno connected to a power in 12v.

From what I’ve been debugging the lib and the Task method of USB class, when a code is read, the HIRQ (CONDETIRQ) detects that the device has been disconnected generating a SE0. Then the device is reconfigured and I can read another code after two configurations.

It may be that reading the code is still being made when the HIRQ register is read?

By their experience the USBHIDBootkbd can be used in this barcode scanner with this HID_Desc or I’ll have to write a HID report parsing?

In the USB_desc my class, subclass and protocol are 3, 1, 1. Following the output of USBHID_desc

0000: 06 00 FF 09 01 A1 01 19 00 29 FF 15 00 25 FF 95
0010: 01 75 08 81 02 19 00 29 FF 15 00 25 FF 95 01 75

Thanks for help me.

Some wireless mini keyboards do work and others don't, what could be happening, apparently the old models worked but the new models didn't, can someone help me solve the problem?
I am testing with the examples that come with the library

Tried to install the lib and do the sample application, got this error.

adktest.cpp:3:30: error: AndroidAccessory.h: No such file or directory

File does not seem to be present.

Hello,

I've a problem with a Keyboard and USB Host Shield libraries, when I press any lock key (CapsLock, NumLock or ScrollLock) the led came on, but if I press again it does not came off, it only came off when I press any other lock key.

Best regards.
