My Arduino UNO's SS is low. I don't know why yours is high.
Note : It's only LOW during communication, not always LOW.
我的 Arduino UNO 的 SS 很低。不知道為什麼你的高。 注意:它只是在通信期間為低電平,並不總是為低電平。
Hi, can you share your test code?
https://github.com/felis/USB_Host_Shield_2.0/blob/master/examples/USBH_MIDI/USBH_MIDI_dump/USBH_MIDI_dump.ino And MIDI keyboard is connected.

Hello: I used Arduino UNO with USB Host Shield, and they can work, but I found USB Host Shield SS pin is high. In MAX3421E data sheet, if SS pin is low, then SPI data can transmit. As far as I understand, SS pin should be low to transmit data, but SS pin is now high and can be used normally.
Thanks.
