I have a TP-Link MR3420 v2 router on an Atheros AR9341 processor.
I want to solder a flash drive (without usb-hub) to expand the space for OpenWRT and at the same time leave the USB port working for other devices (usb-modems, usb-hdd, etc.)
Couldn't find a datasheet for the processor.
Can I solder in parallel, on the legs of an existing usb port?
Or soldered into the processor itself? if in the processor itself, then where?
I would be grateful if you share your experience of "soldering a flash drive into a router"

No way.
The USB specification does not allow you to solder devices in parallel.
There is only one usb port on the processor.
If everything is really bad, then you can solder the second spi-flash. The openwrt wiki explains in detail how to do this.
