Yes! My lucky stick of late is 3GB FAT. But my even older 2GB and 500MB sticks don’t work despite reformatting various ways. My lucky stick used to be a 16GB USB2 in FAT32. But no more, despite many rounds of reformatting various ways after it stopped being recognized.
OK… I guess my assumption was wrong. I know USB anything can be problematic.
One other thing I noticed is that I always have something streaming when I insert the USB (music playing). Maybe try streaming something to see if that works. Maybe the DAC needs an active signal???
I tried that. Didn’t make a difference (with the stick I’ve been using). I have an ancient Lexar 2GB stick that I may try to see if anything different happens.
I find it a bit annoying that PS Audio still hasn’t apparently resolved its “glitchy” USB interface problem.

I tried two old sticks and each has less than 1G memory. Both worked before when I updated FW for MK1 and MK2. But neither worked for the last update.
Waymenchen showed me a different method to get it work finally. I just purchase two 8G sticks for future updates. So, I will have four sticks and if none of them work in future then they are not the problem.
Darn… I was hoping it was something simple we all were overlooking. I bet it will be resolved soon.
I don’t know if this will be useful to anyone, but I have found that when formatting USB drives to FAT32 the partition scheme needs to be set to Master Boot Record. I use Mac, and earlier tonight I accidentally formatted using GUID Partition Map and the MK2 wouldn’t recognize anything on the drive. Never before have I had the MK2 fail to recognize a drive using Master Boot Record, and once corrected that remained true.

If the MkII is happy with FAT32 then you can successfully use Disk Utility on the current macOS Ventura to reformat a USB drive with MBR partition map and a FAT32 filesystem:
- From the View menu choose “Show All Devices”
- From the list on the left select the first icon which represents your USB device
- Click the “Erase” button
- Enter the name you want the disk to have
- Select “MS-DOS (FAT)” as the format
- Select “Master Boot Record” as the scheme
- Click the “Erase” button
If the DAC isn’t happy working with that I can provide instructions on creating a FAT16 partition instead, but that requires typing potentially destructive things into the Terminal.
I use a PC to format and copy firmware files to the USB stick. I also make sure I eject it first before pulling it out.
Are ones with issues using a MAC?

No Mac here. Will double check my Windows format settings and try other sticks again when home again next week.
My old 2MB Lexar was read immediately upon plug in.

That’s good info. Thanks.
Hi Ted,
I have PSA SACD transport paired with DS DAC 2 and although I love the sound when music plays; the crackles between tracks become more and more annoying since it happens on almost every track I play.
Do you have an estimate when this will be fixed?
April 10, the new FPGA will come with the new UI code.
Are you running FPGA 198 or 179? If you are on 179, 198 might help in the mean time. The link to the 198 release is in the first message on this thread.

T-10 and counting
Ted, I am running 198 but the crackling s are still there. I think I heard only pops with 179 but cracklings with 198 before each song plays.
Those are fixed in the next release. AFAIK the next release will have fewer ticks, pops, crackles etc. than any Mk II released so far and few than any release of the DS Mk I. In some cases quieter, in others gone entirely. So far testing is going well.

Thanks Ted.
I am super excited for this next release. Also excited to hear what others think at Expona. @tedsmith you going to show off you new baby there?
No, I won’t be there.
