Don't work USB_Test program #20

Hello,

We're testing with a keyboard connected to the ESP32-DevKit C-32E.
But when I type on the keyboard, I don't see the keys.
GPIO has DP connected to 16 and DM connected to 17, with the other pins disabled.
Do you have any advice?

[Env]
ESP32-DevKit C-32E
Arduino IDE 1.8.19 for windows

Hello @yamachan-hacomono,

thanks for your feedback 👍

Can you please specify the exact keyboard model along with more info on the VCC/GND wiring for this USB port?

⚠️ The keyboard has to be USB Low Speed otherwise it won't be detected by this library, which eliminates most wireless dongles and keyboards/mice for gamers.

@tobozo
thank you for your reply!

VCC / GND is obtained from a regulated power supply and has a sufficient supply amount.
The connected device is a general USB keyboard. Maybe it's doing fast processing and you don't recognize it. The keyboard is Realforce 91UBK-S.

VCC / GND is obtained from a regulated power supply

is GND shared between the ESP and the keyboard as it should?

Realforce 91UBK-S. Price | $200+

that's bad news, given the average price of that device it's probably a USB High Speed device.

one way to verify this is to plug said keyboard to a linux system while running tail -f /var/log/syslog and look for the device detection message: if it doesn't mention low-speed USB device then it's not compatible.

Apologies for reviving an old thread but I have the same issue; I'm building against espressif32@5.2.0 as that's the last version using arudino framework v2.0.5 which is in turn based on the tested ESP-IDF 4.4.2.
I'm seeing no callbacks (read: serial output) when connecting or disconnecting a low-speed USB keyboard or typing on that keyboard. The keyboard is a Cherry Stream, and I confirmed syslog shows low-speed.

I tried various GPIO port combinations to no avail. Full serial output below:

@danieltwagner looks like the keyboard isn't detected

what keyboard model is this? usb information on that device can be collected from a computer using lsusb or similar utility, it will tell if that device supports USB 1.0 or not.

moreover, you can use build_flags = -DCORE_DEBUG_LEVEL=5 in platformio.ini to get more information in the serial console, it should print some information when the keyboard is plugged/unplugged

Thank you for the quick response! Here's what lsusb says:

thanks for that information, it looks like an USB 2.0 device, only USB-LS (1.0) devices are supported

bcdUSB               2.00

USB-LS HID devices are typically vintage stuff from the 90's, anything newer than that has probably moved away from USB 1.0 and isn't supported

Oh I see. I take it the "low-speed USB device" message in syslog was misleading then and even though it's using a slow (1.5mbit) transfer mode it's actually USB 2.0?
