DBI semaphore error

[CaptainKoloth]

I'm trying to back up NSPs from my Switch to PC via USB using dbi, but whenever I initiate the transfer, after a few minutes it will consistently stop and display the error "The semaphore timeout period has expired." What is happening? What can I do about it?

your PC is losing connectivity to the “drive” (your switch)

try swapping out your USB cable.

try rebooting your PC.

make sure your switch shows up properly in device manager (no alerts/errors)

check that yiu have the right driver.

does it work with a small game or just not work at all?

Happened with three different USB cables on two different PCs. Game size doesn't seem to make a difference.

well crap. That’s pretty consistent that somethings not getting set up right on the switch end.

are you able to do other USB related tasks such as mount your SDCard via UMS in Hekate?

Well, that's why I'm here! I can mount via UMS in Hekate.

Perplexed. firing up DBI to see if I can duplicate.

Interestingly, it only seems to be happening with folders- not NSPs. So maybe it's large numbers of files that are confusing it.

Spoke too soon, it also happens with NSPs, though it takes a little longer before it happens.

I don’t know, man. I’m using the latest version they just released a few days ago, I’ve been trying to get it to fail. No luck unless I just flat out whack the tinfoil drivers.

somebody smarter than me want to look at this?

 

[CaptainKoloth]

Appreciate your trying. I don't suppose dbi has any sort of log function?

yes there is. You set it up in the dbi.config file right next to your .nro file…docs for setting it up are here: https://github.com/rashevskyv/dbi/b...7696dafebdf23bf1c97a6/README_ENG.md#dbiconfig

FYI, also tried via Tinfoil and I'm getting the same error. I can see the files on PC, but I can't reliably copy them. I tried connecting to a drive formatted to FAT32 and an exFAT drive on Windows 11 and Windows 10. It's highly repeatable for me. I'm amazed no one else ever seems to have seen this error.

You’ve done a great job isolating what it’s not…that’s for sure.

I’ve never tried this but maybe you could get some insight into what’s going on by sniffing the traffic:

This is all I got in the log of one failed transfer. Not very illuminating.

As far as you got the same issue with tinfoil, this is your PC issue.

 

[CaptainKoloth]

Tried on three different PCs.

Try using TinWoo Installer and NS-USBLoader instead.

Tinfoil registry fix?

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_057E&PID_201D\[DBI VERSION]\Device Parameters]
"DeviceIdleEnabled"=dword:00000000
"DefaultIdleTimeout"=dword:0000EA60
"USBTimeout"=dword:0000EA60

You might need to adapt the VID and PID to your Switch, but hopefully the values will be the same for everyone.

With DBI MTP connected, go to device manager, Portable Devices, and Right-click --> Properties on Switch. Under Details tab, select Hardware Ids property. Then open regedit, go to [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\, and find the key that matches the value you got from device manager. Inside it will be another key that's the DBI version you're using, and inside will be the Device Parameters key. Try to change DeviceIdleEnabled dword to 0, DefaultIdleTimeout to EA60, and create a dword for USBTimeout and set it to EA60.

I'm trying this right now because I'm running into the same issue, so I can't confirm if it helps. But if it doesnt end up helping for me, it might end up helping for you still.

One thing I noticed is that when I got the error, a game produced a 30GB NSP despite the game actually being 17GB (doom eternal), I'm wondering if it somehow fails to properly switch the stream over to a different file, and it just keeps pumping data into the previous file until it realizes something's desynced and it errors out?

Are you sure you dumped base game and not combined nsp with updates and dlc?

I have those disabled, I dump by copying the folder containing base + update + dlcs separately

A retry dumped everything properly
