Default Some routers can be picky with USB storage devices

On a Technicolor TG799vac (Telstra - software version 15.3, firmware version 15.53.6467-510-RA, hardware version VANT-F), I had problems recognizing a specific model of USB flash drive (FAT32 filesystem) I was trying to use as network storage, but this function worked OK with two other USB flash drive (FAT32 filesystem) models I tried.

The questionable flash drive (Dyna Store PA5168A-2MAB) was checked for errors (none were found) and it did previously work on a Netgear WNDR3700v2, and the significant technical details of the flash drive are:

Device Name: Mass Storage
Device Type: Mass Storage
Description: Generic Flash Disk USB Device
USB Hub: No
Vendor ID: 058F
Product ID: 6387
USB Class: 08
USB Subclass: 06
USB Protocol: 50
Power: 200 mA
Capabilities: Removable, Unique ID, Surprise Removal OK

The two other flash drives which worked OK with the router had a different Device Name, Description, Vendor ID, and Product ID.

So therefore, it appears that some routers can be a bit picky with USB storage devices, even though they do not have security functions and/or require specific drivers.

If the flux you have slathered on your workpiece is creating more heat burning away than the torch you are using, then you are soldering correctly.

With how plentiful and cheap storage has become its perplexing as to why we continue to use lossy audio codecs like MPEG....

format the stick with something else.
this issue has been seen before when formatting memory cards on windows for use in the Nintendo WII

Keep trying different things. I am told that SSDs have not been tested (in a USB drive enclosure) with my Linksys WRT-AC1200. But the one I am using now works just fine.

Good luck, and have a happy new year!

UPDATE: Under a Linux serial console when this problematic model of flash drive was plugged in, there was an indication that there was no DPO or FUA support for this model.
