reComputer RK: The Most Powerful Rockchip AI Box for Embodied AI
Hello,
I just received my SeedStudio Recomputer RK3576 and I have a well working machine thanks to the armbian team using the debian Forky image.
I try to understand why i cannot connect a (usb) minipcie modem (already testing 1 year use with Radxa zero 3 W), all usb ports not working anymore!
There is a strange note on schematic pdf :
If the PCIe1 or SATA1 function of Combo PHY1 is
selected, the USB3 OTG1 function cannot be used,
and even the USB2 PHY1 function cannot be used
But they also notice the support of usb link on this minipcie :
LTE LoRa Module: Module:EC20/EC25
WM1302 SPI/USB Version
Zigbee: USB Version
The miniPCIe is connected on USBHUB_HOST3 ← USB HUB external chip → USB2_HOST1 (RK3576 soc).
All USB phy fail, even USB PHY not related to this usb hub.
lsusb didn’t show my usb modem, even if there no usb devices connected.
any input?
thanks
