N450 CG3000Dv2 Unable to access USB ports

Same exact problem. Until recently USB storage has been working fine (other than the perpetual issue on every Netgear model of being very slow) but suddenly it won't recognize ANY of the flash drives that always worked before nor any others I've tried. Yet all of them work properly on a PC. I've tried multiple reboots of the router and even a full reset back to factory defaults. Nothing has resolved the problem. Therefore, it seems likely a new firmware was pushed to the unit that has caused the issue - mine is now on version 3.01.16 and I'm fairly sure the last time I logged into the router prior to this problem it was on 3.01.14.

I haven't contacted Netgear yet because I wanted to search online for a solution first. However, like you, my CG3000Dv2 is just slightly over 1 year old. Nevertheless, I find it unacceptable that Netgear refuses to even look into the problem considering this is still a product being currently sold at retail and advertised as providing USB network storage functionality. Therefore, if Netgear is going to ignore that fact and refuse to address the problem, then I find it perfectly acceptable to have me and my family members (and a couple friends who bought this router on my recommendation) to all start buying multiple brand new ones repeatedly from Amazon, Walmart, Best Buy, Target, etc. and returning them as defective when their USB network storage doesn't work and writing corresponding negative reviews as well. I would suggest others do the same. Maybe when Netgear starts getting back hundreds of these as defective returns, they will finally demonstrate some customer service and assist with resolving the problem. It's sad it must come to this since I've been a loyal Netgear customer for over 2 decades (having personally owned several different Netgear switches/routers/etc and recommending even more to friends and family over the years) but if they are unwilling to return that loyalty then I have no reason to continue offering it.
