So far so good, everything is looking fine and hcxdumptool is able to set monitor mode and channels:

Up to here, everything is still fine. We can set monitor mode and we can set a channel.

Unfortunately the device doesn't receive packets. Neither in monitor mode, nor by iw scan
$ sudo ip link set wlp48s0f4u2u3 up
$ sudo iw dev wlp48s0f4u2u3 scan
$
The green LED flashes during scan, but that's all.
I'm sure I'm missing something, but I don't know what.
Any ideas to point me to the right direction?
If you plug it in and scan with iw, is it the same? I mean, without using hcxdumptool first.
Yes iw first, hcxdmptool second orhcxdumtool first and iw second, both results in the same problem.
First I thought the problem is related to this: https://bugzilla.kernel.org/show_bug.cgi?id=217205#c77 But that isn't the case.
That patch will only affect the RTL8188EU.
If the LED blinks, the chip thinks it's transmitting something.
I wonder if this device needs different initialisation tables because it's „high power”.
Can you compile this driver: https://github.com/Mange/rtl8192eu-linux-driver/ with a patch:

It prints useful information. rtl8xxxu is a bit lacking in that area.
This device definitely needs different initialisation tables:
[127893.559738] RTW: pHalData->ExternalPA_2G = 1 , pHalData->ExternalLNA_2G = 1
[127893.559739] RTW: pHalData->TypeGLNA is 0xa
[127893.559740] RTW: pHalData->rfe_type is 0x1
My cheap, small dongle from Aliexpress:
RTW: pHalData->ExternalPA_2G = 0 , pHalData->ExternalLNA_2G = 0
RTW: pHalData->TypeGLNA is 0x0
RTW: pHalData->rfe_type is 0xff
rtl8xxxu may already have all the code it needs for this device, but it's not enabled. You could try this simple patch:

Unfortunately, this patch will break the „normal power” RTL8192EU devices.
Good price-performance ratio. Good sensitivity. Working fine in combination with hcxdumptool.
All devices collected in rtl8xxxu is cheap, portable sized chips, affordable one..
TL-WN722n v1 was the well-known ath9k_htc. Downgrade
And the TP-Link TL-WN722N (v2) is impressive, too: https://github.com/ZerBea/hcxdumptool/discussions/361#discussioncomment-7551692

I decided to dive into the world of QpenWRT (on Raspberry Pi Zero).
So, I've run it down. The adapters must be set enabled in web gui btw, that was the block. I just finished flashing and run down now, great results 👍
So, I put the 1 chip in AP mode and number 2 chip in monitor, in gui. Fetching PMKIDs like a pro
Working like a charm - good starting point. Thanks
That's great. I will prepare a better patch „soon”. Wanna buy me a present? 😁 https://www.amazon.de/hz/wishlist/ls/1OCIJV31AAT9O/ref=nav_wishlist_lists_1
