Hi, I added an SSD to my Pi4 setup and now my Z2M doesn’t recognize any of my devices anymore and when I force remove them and try to readd them there is just nothing happening. I tried almost everything like resetting Z2M and the controller and installed newest Firmware, downgraded Firmware again. I have all the logs enabled and even the Zigbee-herdsman debug logging enabled but there is just nothing I can see that would indicate any problem.

Presumably you’ve tried moving the dongle around? The SSD may be introducing additional interference that wasn’t there before.
Yeah I tried that but I also ordered a new extension cable which should arrive tomorrow.
Tip; when it comes to Zigbee2MQTT it is better to post to their community here → Koenkk/zigbee2mqtt · Discussions · GitHub
Yeah, Zigbee uses very low-power radios that are very susceptible to EMF/EMI/RMI interference and regardless of the root cause I highly recommend that you read and follow my collected tips here → Guide for Zigbee interference avoidance and network range/coverage optimization (suggest beginning with connecting the Zigbee Coordinator adapter using long USB extension cable to a USB 2.0 port or via USB 2.0 hub in order to be able to move it away from all possible sources of EMF/EMI/RMI interference, and be especially sure that not connecting via a USB 3.x port or USB 3.x hub or even have it be close to any USB 3.x devices and cables to active USB 3.x devices)
Is there a maximum recommended length? I’ve just ordered a 2m one. Overkill probably. 
You just have to follow the USB 2.0 standard (however recommend getting one that has good shieling), anyway I believe the maximum length is 5 meters (or about 16 feet), but you can actually make an even longer USB extension cable if use USB to Ethernet/RJ-45 extender adapter/converter kit (but again recommend get a shielded cable for it). That and more discussed here → Zigbee networks: how to guide for avoiding interference and optimize for getting better range + coverage
