USB: Can't enter a hexdecimal revision no at the USB device filter

[MicK]

I want to create a new USB filter entry using a revision number. But the input field for the revision number allows only 4-digit numbers, no letters (A-F).

[MicK]

no hexadecimal revison-No. possible

[Frank Mehnert]

The revision number has the form of IIFF where II is the integer part of the revision while FF is the fractional part of the revision. For instance, revision 1.0 is encoded as 0100 (16-bit packed BCD). Which USB device has a revision number with a hexadecimal revision? Can you provide the output of

VBoxManage list usbhost

when this device is attached to your VirtualBox host?

[MicK]

The tooltip of the input field of the USB filter box says clearly: "Sets the revision number for the filter. The format for the exact comparison is XXXX, where X is a hexadecimal number. An empty string will match any IDs.". Further, this representation is used also in the USB device Display and you can enter only 4 digits.(see screenshots 2 & 3).

Here is the list of my devices:

Hello Frank, okay, I understand the system and searching for the reason. I have found the bug at line 42 in UIMachineSettingsUSBFilterDetails.cpp and now there are, in my humble opinion, two possible solutions:

1. allow all hexadecimal characters like line 41 (matching the tooltip description)

-> perhaps the value must subsequently be converted to decimal internally to setup the USB-filter correct (preferred solution) OR

2. allow 5 numbers and limited the range (from 0 to 65535 ?) and change the tooltip (bad solution, because everywhere in virtual box the USB revision-no is shown as hexadecimal number -> e.g. device manager)

Unfortunately I had no time previously to set up the build environment and solve the problem directly, but I hope my assist helps to fix it in a future release.. Thx!

[Frank Mehnert]

MicK, actually the tooltip for the German translation is wrong. IIFF is correct, XXXX is wrong. But the output of

VBoxManage list usbhost

is very interesting. Could you also run

lsusb -v

on your host and attach the output to this ticket? The Revision 28.240 looks invalid. According to ​http://www.sprut.de/electronic/interfaces/usb/deskriptor.htm, bcdDevice cannot have no more than 4 digits.

[Frank Mehnert]

MicK, could you provide the informtion I requested?

[Socratis]

Frank, please take also a look at ​https://forums.virtualbox.org/viewtopic.php?f=2&t=79254 especially the second USB device where the SerialNumber is unusual; "12²". Parsing error perhaps?

[Frank Mehnert]

socratis, thanks, but I don't think this is a problem. What I'm after in the context in this ticket is the weird format of the USB revision in some of the USB devices listed above.

[MicK]

Hi Frank, hi socratis,

okay, the (my) main problem is that some manufacturers of USB adapters using a weird format of the usb revision from 0 to 255 instead of BCD-conform values (0-99) and the wrong german tool-tip translation.

But the bcdDevice field is NOT used by any usb driver (inside windows!, Linux ?) (see your sprut link - section bcdDevice ), so that's MAYBE possible to allow all (hex-)numbers in the revision field. The virtualbox devices manager read and convert them correct internally, only the filter input field blocks it ;-) .

See attachment 04 and USB HOST LIST

Thanks for your help & time! MicK

Hi Frank, hi socratis, I just add the usb device(s) with the (wrong) revision id via "Add...selected usb device" to the filter and now all values accepted (attachment 05). After shut down and start up the keil adapter connects automatically, but the peak adapter [1cff] or [1c01]does not so (Virtualbox is showing that the filter is active!). If I change the revision number to 2801 [1c01] the adapter won't connect too :-( (attachment 06)

I know that this is not (directly) the beginning problem, but depends on it. best regards MicK

[MicK]

add usb device via select usb device

[MicK]

change revision no 01c01 to 2801

[MicK]

Update: After consultation with the manufacturers I get updated firmware for the different adapters, so that the integer part is a valid BCD number. The fractional part is still 0xFF or 0xF1. Now does the USB filter and binds the CAN adapter correctly and the automatic connection, when the guest system start up, works. Furthermore, now works disconnect and re-connect, although the revision number is 0x33FF (51 255).
