Hello,
I posted sometimes:

With the last Version 00.04.04.03.05 the login is now working with:

Hauke:
Hi Wolfgang,

sorry to say: But not for me. It is as I write: any four letter (or shorter) username works, anything 5 digits plus: No success.

Or are we talking about different logins? I refer to accessing http://[IP of the scope]/, and then hitting "Network settings". Where do you refer to?

Cheers

Hauke

Since the firmware update to 04.04.SP4, I cannot read waveform data with more than 10 MB via SCPI command.
The 6 MB work, the 12 MB data are aborted at 10 MB. The oscilloscope will then stop sending data. But you can read in data afterwards without any problems. The oscilloscope did not get stuck.
It worked with the previous software 04.04.SP3.

Can anyone confirm that?

Does the same happen when using DSRemote?
At this moment I don't feel like upgrading the firmware of the scope...

No, because you gave no "Steps to reproduce" the error.

No, because you still didn't give any "Steps to reproduce" the failure.

From the webpage of DSRemote:


--- Quote --- Unfortunately, there's a bug in the firmware of the scope that causes connection problems
when your computer uses an xHCI host controller (USBv3.x).
Computers with an EHCI host controller (USBv2) will work fine.
Rigol has been informed about this firmware bug. They acknowledged the bug and said
they have no plans to fix it.
So, if DSRemote generates the error message "Can not read from device", check the following.
Open a terminal and enter

  echo "*IDN?" > /dev/usbtmc0; cat /dev/usbtmc0

If it response like this:

  RIGOL TECHNOLOGIES,DS1104Z,DS1ZA17040xxxx,00.04.04.SP3
  cat: /dev/usbtmc0: Connection timed out

the connection is ok. If not, there's a problem. Check the following:

  dmesg | grep -i xhci | less

This will show you if your computer has an xhci host controller.

  dmesg | grep -i ehci | less

This will show you if your computer has an ehci host controller.
Some computers have both. In that case use an USBv2 port, not an USBv3.x port (blue).

p.s.: not all xHCI host controllers causes connection problems. It depends on the brand and
model of the chip on the motherboard of your computer.
The cause is that Rigol presents itself as an USB 2.0 High Speed device but it uses a packetsize
of 64 bytes. The USB 2.0 protocol specification dictates that highspeed connections MUST use a
packetsize of 512 bytes. Now, some USB host controller chips are "forgiving" and accept the smaller
packetsize. Some USB host controllers are less forgiving and don't accept the too small packets.
You can see the packetsize protocol violation of Rigol when you type dmesg in a terminal after you
connected the scope:

--- Code: ---  usb 3-2: new high-speed USB device number 4 using ehci-pci
  usb 3-2: config 1 interface 0 altsetting 0 bulk endpoint 0x82 has invalid maxpacket 64
  usb 3-2: config 1 interface 0 altsetting 0 bulk endpoint 0x3 has invalid maxpacket 64
  usb 3-2: New USB device found, idVendor=1ab1, idProduct=04ce
  usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
  usb 3-2: Product: DS1000Z Series
