ScanSnap Home 1.4.0 update and release notes

Posted by jpluimers on 2021/09/10

The first stupid thing is that when pressing the “Install” button: it will not ask for UAC elevation, despite the UAC elevation badge:

The second is the release notes from the installer indicate there is more information to be found when clicking, but after clicking it shows exactly the same information:

Update ScanSnap Home to 1.4.0.
Modifications from 1.3.1 to 1.4.0.

– A new feature has been added to perform OCR recognition on an image of a business card or receipt again by marking the necessary parts with a frame on the preview window.

– A new feature has been added to allow users to preview multiple images on the main window.

– A new feature has been added to apply [ScanSnap Manager – Profile] to ScanSnap Home.

– Help menus and contents have been improved, allowing users to find information that they want quickly on the Help.

– Operability for linking with cloud services has been improved.

– Operability for adding and editing profiles on the taskbar has been improved.

– A modification has been made so that you can delete a content data record that is managed in ScanSnap Home even after you delete a file for the content data record in Explorer.

– The waiting time it takes after a scan has been reduced.

– A modification has been made which enables users to use the scan window as soon as it is displayed.

– Operability for contacting your support representative has been improved.

– Fixed the problem that occurs on ScanSnap iX500, preventing the Wi-Fi settings from being configured successfully with an SSID that includes double-byte characters.

– Fixed the problem where the Scan buttons for other users may not be disabled on the touch panel when users are switched.

– Fixed the problem where the scanner turns off even if [Automatic power off] is set to [Never].

– Fixed the problem that occurs when the title of a content data record is changed during text recognition, causing the changed title to return back to the original title.

– Fixed the problem that occurs when scanned images are not managed in ScanSnap Home and when they are linked with a certain application, preventing the scanned images from being saved in a specified folder.

– Fixed the problem that occurs when a connection is established with ScanSnap SDK via Wi-Fi, preventing a serial number from being obtained with the GetScannerInfo command.

– Other miscellaneous bug fixes and improvements have been done.

For details, double-click [ScanSnap Home Update].

Windows on VMware ESXi: fixing “Unknown USB Device” or “The USB device returned an invalid USB device descriptor”

Posted by jpluimers on 2021/08/27

Sometimes, the Windows device manager shows any of the below errots for an USB 3.x device that is physically connected to the ESXi host and passes through a VM (via a virtual USB controller and virtual USB device).

This solution usually works: use a USB 2.0 cable instead of a USB 3.x cable.

If it doesn’t work, then the solutions are the same as when this happens in a pure physical solution:

In my case, I needed a USB connection, because it is the only way to reset a Fujitsu ScanSnap scanner to correct WiFi settings after it gets confused (which happens a few times per year).

The difference for devices with a known driver:

  • USB 3 cable 
  • USB 2 cable

This happened with me on both a ScanSnap iX500 and iX1500, and this did not help (as I was on a more recent Windows version): [WayBack] When setting up your scanner 502: My computer does not recognize ScanSnap iX500 with a USB 3.0 port. – Fujitsu Global.

How to: Reset C by GE Light Bulbs – turning things off and on again, and again, and again…

Posted by jpluimers on 2021/08/27

You know the old helpdesk joke about “turning it off and on”, right?

GE did that on steroids for their C light bulbs.

It is an off, on, off, on, off, on sequence that depends on the firmware version which nobody knows.

Both procedures:

  1. start with the light bulb being on for at least 5 seconds
  2. have a sequence of off (for 8 seconds) and on (for 2 seconds)
  3. ends with the bulb to flash on/off 3 times (apparently it ends in the “off” position)

Do not mix up the off and on times, or you have to restart again.

So step 2 becomes this:

  • for firmware 2.8 or later: turn off and on 5 times.
  • for firmware 2.7 or earlier: turn off and on 6 times.

The recommend counting using Mississippi seconds (am I the only one having to check the spelling of that 3 times?).

No counting mechanism beats using a watch or clock.

Is it more accurate to count seconds in Mississippi’s, or one-thousandths
byu/MrSparta618 inShowerthoughts

They even made a video about it lasting 3+ minutes.

The video has a great comment thread.

Better disconnect your Samsung TVs from the internet, as they can remotely disable them for whatever reason they see fit

Posted by jpluimers on 2021/08/25

Oh nice: [Wayback/Archive.is] Samsung can remotely disable their TVs worldwide using TV Block.

This means:

Disconnected, any apps needing internet connection won’t run.

Those apps usually work more reliable on an Apple TV or similar device that plays over HDMI anyway.

In addition, it will also prevent Samsung to show adds on your TV.

So disconnecting it is a win-win-win situation.

 

Note: you could already block apps and adds, see:

Maybe those blocks also block blocking.

MikroTik RB960PGS hEX PoE powering PoE devices: ensure you get a 48V power supply

Posted by jpluimers on 2021/08/24

By default, the [WayBack] MikroTik RB960PGS hEX PoE comes with a 24V power supply.

Most PoE capable devices cannot be powered by 24V but need 48V. I wrote about this before in the midst of the long post Linus Torvalds – Google+: Working gadgets: Ubiquiti UniFi collection (and a whole bunch of Unifi/Ubiquiti/Ubtn links)

So now I re-mention it in a much smaller post so it easier to find back, and a few links to Power over Ethernet – Wikipedia, where especially these bits are relevant:

  • The PoE Standard implementation for 802.3af (802.3at Type 1) “PoE” requires DC 44.0–57.0 V.
  • Of the PoE Non-standard_implementations, some common Passive specifications include:
    • 24VDC 0.5A 100 Mbit/s or 1 Gbit/s
    • 24VDC 1.0A 100 Mbit/s or 1 Gbit/s
    • 48VDC 1.0A 100 Mbit/s or 1 Gbit/s
    • 56VDC 1.0A and 2.0A 1 Gbit/s (used for 45W+ load point to point microwave and millimeter band radios

The 24V is what MikroTik sticks to with their default power supply.
