Hi,
I get this error when i try to flash an image via sdkmanager
ERROR: Could not write to '/dev/ttyUSB0', Windows API WriteFile failed! Your device is probably *not* on this port, attempted 100 times
it seems to start writing but crashes for some reason
erase steps and flash_cdt_fullbuild pass fine

I am on Ubuntu 20.04 i tried to flash native, in docken and on windows(MULTIDL_TOOL_v1.0.14) all failed
lsusb sees the device as Qualcomm, Inc. Gobi Wireless Modem (QDL mode), ttyUSB0 is only ttyUSB*
EDIT:
SOLVED !
Problem was faulty power adapter, device appears to work with power from usb, but crashes whei I put any load to it.
Device only sent data to debug port when i plug in usb-c, power adapter didn't seem to start the device so I assumed it was the problem and it is.
It works now, so double check power adapter
Hi Customer
From the error report, it can be seen that the serial port is not recognized,
Is the device still connected to the host before and after the error is reported,
Is there any device 9008 (QDL) after executing lsusb command
Before entering sdkmanager burning, execute: sudo systemctl stop ModemManager
First method:
In addition to synchronizing the latest version of sdkmanager, you can also synchronize the previous version to see if there are the same problems, as shown in the following figure.
Second method:
Do you have a QFIL burning tool? This is the burning tool of the Qualcomm platform. If you have this tool, I will guide you to use it to solve problems.
