I am using RG520N-EU module. To communicate, i have added option driver and added the VID & PID into the option_ids.
VID= 0x2C7C
PID=0x0801
But the device is not detecting. I was following UMTS LTE 5G Linux USB Driver User Guide. Is there anything I missed?
With lsusb can you see the VID and PID?
If you cannot see the VID and PID with lsusb it means something wrong with the hardware side.
I have resent the LINUX driver to you. Please try again.
Hi Bean.Wang-Q
yes, i am not able to see VID and PID with the lsusb command when I have connecetd through USB type c interface. The EVB i am using is RTA001EV-EVB and I have turned on the module by pressing PWRKEY and the D0202 is lighted up.
But the module is detecting through UART Main interface.
Please show us how you connect it with the Linux host. Can you show a photo?

I think maybe it is using the wrong interface.
What is the EVB like? Seems not from Quectel…
What you used is already the USB port.
But it seems the RG520N not power on.
Or maybe you can try another USB-C cable?
HI..
What user manual says is
Press the S0202 (PWRKEY) for at least 500 ms and the module will be powered on and D0202
(operation status indicator of the module) will light up.
The D0202 LED(yellow) is ON actually, sorry for the low quality image.
Also, I tried with another USB cable too. But the issue still persists.
If you login in the modem via the debug uart, can you make sure the modem boot up?
Thanks. I have connected the modem through debug UART port, and the error messages are given below:

I’m not sure whether this is causing the issue. Anyway, I am able to access the login menu

If you can login in the modem via debug uart. You can try send AT command over /dev/smd11 or /dev/smd9.
Maybe the modem is in PCIe EP mode.
If we press the USB_BOOT button, and then power up the module, can see the 05c6 9008 with lsusb?
Can you share the login id and password for debug UART interface? I couldn’t find any documentation regarding that. But wwan0 interface for connecting internet, can’t be accessed through that, right?
The 05c6 9008 is also not detecting through the type C USB interface, after press USB_BOOT and then power up the module.
The username is root, but for the password it need more check.
Okay.Thanks
I have kept the S1601 as that(0011). But I am still not able to get 05c6 9008 with lsusb.
Or maybe you can try another TE-A module. As I think, maybe there is something wrong with the EVB 、Module、USB Cable.
yeah thanks a lot.
Sorry actually. the module was not pressed into the EVB correctly. It is working fine now properly.
