[partially SOLVED]USB-Serial cable on XE300

[crabtang]

[SOLVED]
The XE300 we purchased is the model with a battery, as the without-battery model is out of stock at that time.
while we do not need the internal battery and charging the battery releases more heat. so we removed the internal battery.
I believe this caused the problem. see the below link for more info.

/etc/init.d/init_gpio bug on ar300m (and anything but xe300)

Upon looking into why GPIO16 was exported on my ar300m (for Ar-300m i2c - #4 by gadgetoid) I came across /etc/init.d/init_gpio: root@GL-AR300M:~# cat /etc/init.d/init_gpio #!/bin/sh /etc/rc.common START=01 set_xe300_usbpower() { . /lib/functions/gl_util.sh model=$(get_model) #For xe300-no-battery, export gpio16 and turn on the USB power [ "$model" = "xe300" ] && [ -d "/sys/bus/usb/devices/1-1.4/1-1.4:1.0/ttyUSB0/" ] || { echo 16 >/sys/class/gpio/export …

once we restored the battery, the USB port gets the 5V power.

however, we still need help to make it works on the battery removed XE300

Thank you.

while it is so weird. I tried excatly same procedure on another XE300, and no luck.
I use a USB port tester and found that the USB port does not have 5V voltage output, except only few seconds after XE300 was powered on.
keep working on it…
============================================================

Hi There,
We purchased a few dozen XE300s for our project. but we are now facing problems letting the USB-Serial cable work on XE300. We tried different cables with almost all chip brands (CH341, PL2303, FTDI…).
For sure, All the drivers were installed. Tried on the firmware version 3.212 and 3.216, with just factory default settings and packages, plus only USB-Serial cable drivers and the usbutils package were installed.

There is no response after any cable was plugged into XE300.

With the lsusb command, it listed four devices:

I can confirm that CH341 must be working because we are using it.

[crabtang]

for the XE300 with battery model, it works with any USB-serial cable when the driver was properly installed. However, if you removed the internal battery from XE300, it seems that a script turned off the power of the USB port during the initialization. we are looking for a solution…

[crabtang]

@galenzhao, any solution?

[galenzhao]

have you tried this

echo 16 >/sys/class/gpio/export
echo out >/sys/class/gpio/gpio16/direction
echo 1 >/sys/class/gpio/gpio16/value

I have same problem , After I removed the internal battery, I can’t access the usb prot any more .

now the usb cant’ use
please help

[alzhao]

For XE300 with batteries, if you remove battery, the USB port will not have power.

This cannot be controlled via the GPIO. The GPIO control can only be used for non-battery version.

[tei]

@alzhao
after removed battery, then I give a 5v to the battery jumper . then USB port have power. My usb device is a usb gps receiver, I can see the device work ,the usb has a red led on. but I can’t get the usb connected.
before I removed battery , the usb use /dev/ttyACM0.
I attached the device information below, please help 。

Even didn’t think this is a solution. But this should work.

Can you get the log when you plug in the usb device?
