SD card detected but not assigned a device

I have a Dell XPS 14 notebook which comes with a SD card slot. I plug in my SanDisk 8GB card from my camera and the following shows up in dmesg:

[821605.639247] mmc1: cannot verify signal voltage switch
[821605.750637] mmc1: new ultra high speed SDR50 SDHC card at address e624

And that's it. The card is not assigned to any device. lsmod seems to indicate that I have the required modules loaded:

± % lsmod | egrep 'mmc|sdhci|sd'                                         
sd_mod                 31361  3 
rtsx_pci_sdmmc         13911  0 
scsi_mod              132250  4 usb_storage,libata,sd_mod,sr_mod
sdhci_pci              12604  0 
sdhci                  28820  1 sdhci_pci
mmc_core               95465  3 sdhci,rtsx_pci_sdmmc,sdhci_pci
rtsx_pci               32305  2 rtsx_pci_ms,rtsx_pci_sdmmc

lspci also shows the SD card controller:

03:00.1 SD Host controller: Realtek Semiconductor Co., Ltd. RTS5209 PCI Express Card Reader (rev 01)

But fdisk -l just shows my hard drive

± % fdisk -l      

Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors

/dev/sda2      1050624    976773134 465.3G Linux filesystem

Anything else I need to do to get the SD card assigned to a device so I can mount it.

Re: SD card detected but not assigned a device

Is there an issue with SDHC cards? I founds some posts on the Mint Linux forums with what seems like the same issue and this card is also an SDHC card.

Re: SD card detected but not assigned a device

I found that if I reboot the notebook with the SD Card in the slot it is detected and assigned to a device. But I'd still like to be able to just insert the SD card and have it done.

Re: SD card detected but not assigned a device

It's considered a removable drive.  I have a USB card reader that if I insert it after the computer has been booted it gives me a little trouble, but having it inserted on booting it wants to put the device in a different order.

Re: SD card detected but not assigned a device

I can mount USB sticks just fine though. I'm not sure if it's just this SDHC card which is an issue but I don't have any others to test with at the moment.
