25H2 unusable

[Marc Antheunis]

hi since upgrading to 25H2 (which should be better) i'm having a lot of issues:

1) a simple usb smartcard reader can't be connected any longer to my win10 vm - this worked like a charm before the upgrade -> MAJOR ISSUE

2) shared broadcom (!) contacted smartcard reader is not usable since it takes MINUTES to readout a smartcard

3) ENORMOUS keyboard lag, i literally have to wait for my keystrokes to appear in this case window (this is the same on w10 and w11 vm) AND that vulkan rendering thing is already turned off

4) outlook in w11 vm has a lot of gui artefacts and keyboard lag - same remark as 3)

so really what is going on?

anyone any solution for this?

i'm forced to downgrade cause 25H2 is not workable...

it seems that reinstalling 17.6.4 solved the most issues, only thing that remains although better is the keyboard lag...

This is probably https://community.broadcom.com/vmware-cloud-foundation/question/after-25h2-upgrade-connect-removable-usbs-intermittent-errors-usbarblib-received-message-size1701667190-exceeds-maxmium-size4096 .  You can confirm by checking if the vmware.log file contains a line that looks like:

USBArbLib: Received message size(1701667190) exceeds maxmium size(4096).

(That line should be easy to search due to the typo in "maximum".)

3) ENORMOUS keyboard lag, i literally have to wait for my keystrokes to appear in this case window (this is the same on w10 and w11 vm) AND that vulkan rendering thing is already turned off

4) outlook in w11 vm has a lot of gui artefacts and keyboard lag - same remark as 3)

This is probably a rendering problem and not actually keyboard lag.  You could try seeing if adding the following lines to your VM's .vmx file helps:

mks.vk.syncPerEndFrame = "TRUE"
mks.dx12.syncPerEndFrame = "TRUE"

looked for usbarblid in the saved logs, no entry for maxmium - in my case the usb device can't be connected to the vm, so i think my case is different...

as for the keyb lag, those settings do not work, disabling 3d acceleration and keyboard.vusb.enable = "TRUE" does apparently...

Can you share the logs so we can take a look at the potential issue?

-------------------------------------------

[Marc Antheunis]

since i reverted back to 17.6.4 i guess the logs will be irrelevant?

and i'm not reinstalling 25H2 for now... i need to be able to connect usb devices

Yeah, it's better to check the log with 25H2. Feel free to reproduce the issue then send us the log anytime.
