USB not recognised.

Hi,

I decided that it was time for a laptop that doesn’t burn my lap. So I got myself Lenovo Ideapad 310-15isk. So far, so excellent. But it doesn’t seem to want to recognise any some devices I connect to it. For instance I have Inkbook Prime that I like to put some more books onto, the previous laptop recognised it right away, but the Lenovo doesn’t want to connect even though the device itself says that it is connected.

Is the capacity of the USB Stick larger than 32 GB?

  • If so, then, it’s almost certainly formatted with “exFAT” which is not supported by Leap 15.1.

[HR][/HR]Please note that, exFAT support is currently being introduced into the Linux Kernel but, there’s considerable discussion happening to decide exactly which exFAT driver will finally be used to support the larger Flash File systems …

That is rather vague. What does the system say itself?
E.g. the diffeneve between a

lsusb

before and after you connect should show a difference. Does it not?

@dcurtisfra assumes this is about mass-storage devics. Is your experience indeed restricted to USB storgae. There are many types of devices using USB connection.

Leap 15.1 has full support of exFAT.
Just install “exfat-utils” and “fuse-exfat” packets.
For creation exFAT partition use this instruction.

Yes, I know but, those packages are being maintained by someone living in Russia and, therefore, he or she is out of the reach of Microsoft’s licensing lawyers …

  • Bottom line, if you’re living in a country where you could be extradited to the USA on charges of licensing infringements, think very carefully about installing those packages.
  • This is also the reason why I paid extra for the exFAT license on my QNAP NAS – which is also Linux system …

[HR][/HR]Or, wait for the Linux Kernel which supports exFAT which, has agreements in place to work around the licensing issues …

Only for Info:

On 28 August 2019, Microsoft published the exFAT specification[7] and released the patent to the OIN members.[43] Based on these, Linux kernel developers have begun development to add support of exFAT to the kernel.[44]

The only device mentioned is an android e-reader with total 8GB internal memory and a SD card slot with a maximum supported capacity of 32GB.

Isn’t this a case for Kconnect or somesuch?

With my old Kobo e-reader the removable SD card is set up on first use with the e-reader and can then be inserted in the laptop. It automounts and files (books, etc.) can be copied to and from the appropriate folders.
